Design Web Format (.DWF) Friendly Extension

Autodesk has created a secure format for an image file, the File Extension DWF (Design Web Format). This format allows the data to open and print them without having to use the software. two other advantages of the compression ratio is small and you the ability to determine the design of the data will be entered into the file. additional component is the third Freewheel, which appeared in 2007.
Freewheel itself is billed as an online "translator" that allows the display of any kind. back to File Extension DWF, this program is also supported AutoDesk AutoCAD, IMSI TurboCAD, and also many others. File Extension DWF latest issue of version 6, which is organized as a container file. can also be opened using a standard file compression is used. so not too for making us a full day working.

but there are also a few common errors associated with various CAD programs that can not export the File Extension DWF correctly. file for this problem generally can not be accessed by AutoDesk Design Review. Don't Worry, because there is no permanent damage caused by this problem.

Panasonic announces pricing, availability for Lumix GH1

Announced at PMA 2009, the Panasonic Lumix DMC-GH1 will be rolling out to retailers in early June. As expected based on previously announced European pricing, the new HD-capable model will command a hefty $1499.95 kit price when it hits stores next month.

The GH1: A refresher course
Based on Panasonic's original Micro Four Thirds concept, the Lumix DMC-G1, the GH1 adds the ability to capture 24 fps full HD (1920x1080) video, or 60 fps 720p (1280x720) movies as part of the camera's live view functionality. Built around the same full-time live view platform that powered the G1, the GH1 uses DSLR-style interchangeable lenses, but eliminates the traditional DSLR's mirror and optical viewfinder – reducing the camera's size and optimizing it for full-time live view.

A 12.1 megapixel sensor provides capture for both stills and video, and like the original G1, the GH1 features an articulating 3.0 inch LCD with a very fast 60 fps refresh rate.

To support the needs of video (i.e. near-silent focusing, quick AF response), Panasonic also announced a video-specific 14-140mm f/4.0-5.8 Lumix lens with the GH1. Providing coverage equivalent to 28-280mm in 35mm terms, the new Lumix G Vario HD lens will be available in June as well as part of the GH1 retail launch.

For more info on the GH1, have a look at our original launch announcement as well as our hands-on preview of the new camera and lens combo.

Retail details
The GH1, packaged in kit form with the new 14-140mm video-ready lens, will be up for pre-order before the official retail launch on Panasonic's website. Per Panasonic, the new camera will only be available in black.

HP ProBook 4510s Review

The HP ProBook 4510s is the latest 15.6" business notebook designed to provide solid performance at a low price for small and medium businesses. If your company wants the HP Elitebook 8530p but doesn't have the budget to spend $1,350 per laptop, the ProBook 4510s might be a good alternative at a starting price of just $529. Is this budget-priced business notebook destined for success? Take a look at our full review to find out.

Our pre-production review unit of the ProBook 4510s is configured as follows:

* Intel Core 2 Duo T6570 Processor (2.1GHz, 2MB L2 cache, 800MHz FSB)
* Microsoft Genuine Windows Vista Business (with option for Windows XP downgrade)
* 15.6-inch LED-backlit anti-glare HD display (1366 x 768)
* Intel Graphics Media Accelerator 4500MHD
* 2GB DDR2 800MHz RAM
* 250GB 5400RPM HDD
* LightScribe DVD+/-RW Optical Drive
* WiFi (802.11a/b/g/draft-n), Ethernet, Modem, and Bluetooth Connectivity
* 8-Cell 63WHr Battery
* Limited 1-year standard parts and labor warranty
* Dimensions: 1.25" x 14.6" x 9.83"
* Weight: 5.8lbs
* Price as configured: $749

Build and Design
The HP ProBook 4510s is a business notebook designed to meet the needs of small and medium businesses ... in other words, it needs to have a good balance of features and security at a low price. That said, small and medium business notebooks tend to have a very basic build and deign in order to help bring down the cost of production. At first glance, the ProBook 4510s looks very similar to a HP EliteBook 8530p with a new keyboard and all black finish. Unfortunately, the design similarities stop there.

HP received much praise for the strong magnesium alloy chassis used in the EliteBook series of business notebooks. Unfortunately, in order to lower the cost and weight of the notebook the ProBook 4510s is constructed mostly of plastic. The base of the laptop flexes heavily under pressure, the palmrests likewise bow under the weight of your wrists, and the back of the screen lid is similarly prone to flex. The plastics used in the 4510s should hold up fine if the notebook is being used as an office desktop replacement, but the chassis might not survive multiple drops off a desk or the kind of abuse you expect from a mobile workforce. On the bright side, the new keyboard is pretty firm except for a very minor amount of flex around the directly above the optical drive (more on that later). The key point to remember in this section is that the ProBook 4510s looks pretty nice, but isn't as rugged as more expensive business notebooks.

Screen and Speakers
The ProBook 4510s comes equipped with a 15.6" anti-glare display with a 16:9 widescreen ratio. At 1366 x 768 pixels, this 720p high-definition display is perfectly usable and features good color and contrast. We know many people are concerned about the transition from 16:10 to 16:9 ratio screens (because this means less vertical resolution) but the difference is so minor that the vast majority of notebook users will never have a problem.

Horizontal viewing angles are quite impressive and you only start to notice some color shift after you get 75 degrees off center. Vertical viewing angles are only average as the screen begins to wash out from above and colors begin to invert from below after about 45 degrees in either direction.

Keyboard and Touchpad
The full-size keyboard on the 4510s is a completely new design for HP and provides fantastic spacing between keys for typing as well as a dedicated number pad (a major plus for businesses that use their computers for number crunching or data entry). Each key is relatively flat with a nice matte texture and the keys sit above a glossy black support frame. The support frame surrounding the keys is quite firm thanks to the design of the chassis which adds additional support for the keyboard. The only obvious area of flex in the keyboard is when you press on the number pad keys. Keep in mind, however, that we received a pre-production unit, and HP claims that the production units shipping to customers have even better support against flex.

Performance and Benchmarks
Our pre-production ProBook 4510s came with the Intel T6570 processor, clocking in at 2.1GHz, and Intel integrated graphics. Discrete graphics will be available at a later date, but discrete graphics will obviously increase the cost of the notebook. A 250GB 5400 RPM hard drive was also included, which helped applications load without much lag. This notebook didn't really exceed our expectations in terms of performance, but the 4510s has more than enough power to handle Microsoft Office or even very basic video work.

The obvious bottleneck in terms of performance here is the use of Intel graphics, but considering the small and medium business buyers interested in this notebook don't care about the ability to play video games or edit HD video, this isn't a major concern.

Heat and Noise
During normal use (browsing the web or working on a text document) the ProBook 4510s remained relatively cool but not very quiet. The exhaust fan seemingly runs a full blast when the notebook is plugged in, so your coworkers might hear what sounds like a distant hair dryer in a quiet office. When doing tasks that stress the processor and graphics, the laptop's fan works hard to keep this laptop cool. This is something of a mixed blessing in that while noisy, it helps to lower the internal temperatures and helps extend the life of your notebook components.

Finally, we recorded the following external temperatures using an IR thermometer after running two consecutive PCMark05 benchmarks. This should serve as an indicator of how hot the notebook will get after about 30 minutes of serious use. All temperatures are listed in degrees Fahrenheit. It's obvious that the bottom of the notebook near the wireless card, processor, and graphics are the hottest parts of the notebook.

Battery
HP offers two different batteries with this notebook. The base configuration the ProBook 4510s comes with a 6-cell 47WHr battery while the $749 configuration comes with the 8-cell 63WHr battery. The battery life of the extended life 8-cell battery is a little better than average, but not amazing. During our timed tests, with the laptop set to "high performance" mode, wireless active, and 80% screen brightness, the 4510s lasted for 5 hours and 10 minutes with a power draw of about 11.1watts. Battery life can also be extended using the "power saver" power profile in Windows Vista.

Conclusion
The HP ProBook 4510s is a solid, though not overwhelmingly impressive small and medium business notebook. Compared to similar notebooks like the Dell Vostro 1510 and 1520 or the Lenovo ThinkPad SL500, the ProBook 4510s is more impressive than the Dell and is either better or worse than the ThinkPad depending on configuration. Whether you're a small business owner looking for a low-cost notebook for yourself or a medium business needing desktop replacements for a few dozen employees, the ProBook 4510s will get the job done.

Still, things like the plastic construction, uncomfortable touchpad design, and difficulty of upgrades might give potential buyers reasons to reconsider a purchase. Additionally, the fact that HP charges almost twice the price for custom configurations (CTO) means that business buyers are almost forced to choose pre-configured models.

Bottom line, the HP ProBook 4510s is a fine notebook for its intended market, but if HP made a few simple changes to the design and purchase options then business buyers would have even more reasons to buy this laptop.

Pros:

* A great price for a 15.6" business notebook
* Nice keyboard ... despite some flex
* Attractive design and relatively light weight

Cons:

* Not-so-great build quality
* Custom configurations are overpriced
* Touchpad buttons are just plain horrible
* Too difficult to upgrade

HP Mini 2140 (HD Update) Review

With more companies entering the netbook market the one thing that is starting to set different models apart is the quality of the keyboards.

Build and Design
The HP Mini 2140, like last year's Mini-note 2133, has a great design. Everyone in our office agrees that this ultra-mobile laptop has a solid chassis and attractive look. The brushed aluminum and plastic casing is durable and hides fingerprints well. It also keeps the Mini 2140 lightweight; only weighing in around 2.4 lbs as configured. The sleek business appeal feels at home in the corporate world, but the Mini 2140 is targeted toward students as well. One look at this machine and you can see why. Who wouldn't want an inexpensive mini notebook to toss in a backpack between classes, especially one that pretty much has a full-size keyboard?

HP was smart to keep the design of the 2140 mostly unchanged from the 2133. Nothing about the Mini 2140 feels cheap. The chassis is solid thanks to a combination of aluminum, plastic, and a magnesium alloy support structure inside. The larger 10.1" display is beautiful and easy to read indoors despite putting off some significant glare outdoors because of the protective coating. The Mini 2140 also comes with enough ports and storage capacity (thanks to the 160GB hard drive) that you might even consider using this business-grade netbook as your primary computer.

As I mentioned above, the keyboard is almost full size. It is 92% of a full sized keyboard, which is quite impressive for such a small form factor. It is much more comfortable to type on compared to the keyboards found on most 10-inch netbooks. However, the touchpad can be awkward since the placement of the right and left touchpad buttons are on the right and left sides rather than beneath the touchpad. As you can see from the pictures in this review the Mini 2140 also has neat power and Wi-Fi switches that light up and change from blue when on to orange when off.

Screen
HP uses a LG LP101WH1 LED-backlit panel under the glossy plastic cover. The display actually has a matte finish, which probably helps lessen reflections between the panel and outer cover. HP lists this panel as having a 200 nit brightness rating and a 400:1 contrast ratio. These figures are in line with what we observed in our testing. The screen brightness was in line with most full-size notebooks, but didn’t appear as bright as other netbooks. I think part of this is the Infinity cover and the higher resolution panel. Colors were bright and vibrant, making most images “pop” out at you from the display. Outside of a few high-end workstations I think netbooks offer some of the best color saturation levels. Vertical viewing angles were above average, with minimal color distortion at viewing above or below the optimal viewing angle. Horizontal viewing angles are better with colors staying accurate at wide viewing angles; although as the screen appears darker, reflections off the Infinity cover start to overpower the display. HP’s technical specification lists the official viewing angles at +/- 30 degrees horizontal and +/- 10 degrees vertical.

The higher resolution display is a huge benefit compared to the standard 1024x576 screen option for one reason; menus in Windows are almost all designed for a minimum height 600 pixels. It is a pain having to drag menus above the screen to find a cancel or confirm button. Other added benefits might include viewing a document and a webpage at the same time or editing large photos. Just be aware that if you have a hard time viewing small text on a screen, the HD display might not be the right option for you.

Viewing outside would be very difficult unless it was very late in the day, or it was overcast and you were under the shade of a tree. The added reflections from the additional screen cover make viewing in bright conditions difficult, making you change your position often to find a new sweet spot where a light isn’t bouncing off the screen into your face. Another problem we saw first-hand with the screen cover is its ability to capture dust between the layers. Some specs of dust were big enough to cast shadows on the display where the smaller ones just looked like white dots as they reflected light from overhead. On a normal screen dust is easily removed with a soft cloth, where this design requires full disassembly to carefully remove any dust without introducing more. In the picture below all the white specs of dust are ones trapped beneath the glossy surface. We tried cleaning the dust out ourselves using a cloth and compressed air, which took care of the big pieces, but still left a lot of small specks behind.

Keyboard and Touchpad
The keyboard on the Mini 2140 is simply fantastic. Last year we said the keyboard on the Mini-note 2133 "is the best keyboard we've seen on a notebook this small." That statement holds true for the new Mini 2140 as well. Sure, you can find better keyboards on larger notebooks, but HP currently has the best keyboard we've tested on 10-inch and smaller netbooks. The keys have the silver "HP DuraKeys" finish that makes them resist dirt and makes the letters printed on the keys last longer over time. The surface of the keys are also smooth to the touch.

Regardless, the most important thing to remember about this section of the review is that the Mini 2140 has the biggest and best keyboard you will find on any netbook or notebook with a 10-inch screen. It is literally almost a full-sized keyboard, so writing papers for school or reports for work is a breeze. You won't see spelling errors due to hitting the wrong keys as often as you might with the tiny keys on most netbooks. I didn't notice any signs of keyboard flex and really liked that most of the keys were full sized except a few. The tilde (~) key and the number "1" key are smaller than the rest of the numbers, which was quite odd. The space bar was also a little smaller than normal.

As mentioned previously, most people find using the touchpad on the Mini 2140 a little awkward. The right and left click buttons are what catch you off guard. The buttons are located on the sides of the touchpad and it's easy to forget where they are located if you're used to a regular touchpad. I would have liked the palm rest area to be a little bigger so the buttons could have been relocated below the touchpad like on standard notebooks and most netbooks. The button above the touchpad is a convenient feature that turns the touchpad off and makes it inactive when you are typing or using an external mouse.

Input and Output Ports
Every netbook on the market requires one minor compromise due to the ultra-mobile form factor: limited port selection. You simply cannot accommodate the standard array of ports you'll find on larger notebooks in a computer this small. That said, HP did a remarkable job packing as many ports as possible into the Mini 2140. The complete list of ports includes:

* One ExpressCard/54 slot
* Secure Digital (SD/SDHC) card reader
* Two USB 2.0 ports
* VGA out
* Power connector
* RJ-45/Ethernet
* Stereo headphone/line out
* Stereo microphone/line in

Overall, the port selection is amazing for a notebook this size. However, we would have like to see one of the USB ports replaced with a combo USB/eSATA port. HP uses combo USB/eSATA ports on almost all of their larger notebooks and the combo port allows you to use either USB devices or eSATA devices such as high-speed external storage drives. Considering how easy it would have been to make one of the USB ports a combo port, we're a little surprised HP didn't do that.

One additional thing worth mentioning regarding ports is that HP doesn't offer built-in 3G WWAN (mobile broadband from a provider such as AT&T or Verizon) with the Mini 2140. If you want to stay connected to the internet via WWAN you have to use an adapter card in the ExpressCard slot or one of the USB ports. It's sad to see that HP doesn't offer the option considering that smaller netbooks like the Dell Inspiron Mini 9 offer built-in WWAN.

Performance and Benchmarks
If you've read our reviews of other netbooks that use the Intel Atom processors then you know that overall performance with the Intel Atom platform is very reasonable for most daily activities like web browsing, email, using Microsoft Office, listening to music, and even watching movies. You can even use photo editing software like Photoshop Elements or GIMP. That said, the Mini 2140 doesn't make the ideal photo editing tool because of the low-resolution screen and the fact that the Atom processor is slower than a faster notebook or desktop when editing large image files. You can play some basic games on the Mini 2140, but don't expect to play Crysis or Left 4 Dead at 60 frames per second ... or at all.

Audio
The built-in speaker performance on the Mini 2140 was nice, but not as impressive as the superior speakers on last year's HP Mini-note 2133. In order to accommodate the larger screen in the 2140, HP removed the large speakers next to the screen and used a pair of smaller speakers integrated into the chassis of the netbook. The end result is the speakers produce weak sound that's good enough for basic web browsing and online chats but doesn't provide a satisfying entertainment experience.

The best possible audio performance with this netbook comes via the use of external speakers or headphones. The audio output from the headphone jack is quite good and provides excellent, distortion-free sound for headphones or external speakers.

Heat and Noise
The ultra low voltage VIA processor in last year's HP Mini-note 2133 generated far more heat than we typically expect from ultra low voltage processors. Temperatures on the new Mini 2140 are thankfully much, much more comfortable thanks to the use of the Intel Atom processor. Temperature readings taken from the outside of the aluminum and plastic chassis rarely spiked above 95 degrees Fahrenheit ... compared to well above 110 degrees Fahrenheit in the previous generation.

The cooling fan was usually running at low speed during our tests and rarely increased to full speed. Most of the time the fan can't be heard even in a perfectly quiet office environment ... unless you put your ear next to the fan exhaust.

Battery
Battery life with the 6-cell battery option was great for the average road warrior who needs to work on the go without wondering why they might plug in. In our test with the screen brightness set to 70%, wireless active, and XP set to the laptop/portable power profile the system stayed on for 5 hours and 26 minutes. If battery life is all that you are concerned about the ASUS Eee PC 1000HE got 7 hours and 36 minutes on its extended battery, but doesn’t include a higher resolution screen option.

Conclusion
The HP Mini 2140 is a very solid netbook that offers an amazing keyboard instead of something condensed that might be difficult to type on for extended periods of time. It wooed us last time we reviewed it, and it gets the same response again now that it offers a higher resolution screen. The other alternatives at this time for a comparable resolution screen is turning to the Sony VAIO P, at the starting cost of $899, or the Dell Mini 10 for $484 for similar configuration. Our big complaint with this model is the glossy plastic layer over the display, which adds glare and created a trap for dust. This is one cosmetic change that might look great on paper and in pictures, but in real life becomes more trouble than it's worth. Overall we were impressed with the excellent battery life, great build quality (except of the dust), and the starting price of $479 for the configuration we reviewed. If HP offered the Mini 2140 with a plain matte or glossy LCD, sans cover, this would be hands-down the best netbook money could buy. With the cover it is still an excellent netbook, but it loses some of its attractiveness.

Pros:

* Excellent keyboard
* Very good extended battery life
* Higher resolution

Cons:

* Glossy screen cover adds a lot of reflection
* Second screen layer can trap a ton of dust

Scosche reCoil iPod/iPhone Car Charger Review

Nowadays everybody is jumping on the iPod car charger scene but it’s not too often you see one of these. Tailored to de-clutter your dash area while giving your iPod/iPhone all the power it needs comes the 3 foot retractable Scosche reCoil. Lightwieght and pocket size, the reCoil will be an ideal choice for those looking for an automotive charging solution.

Operation is dead simple, requiring you to plug in either end to their appropriate sockets. A vivid blue LED shines to let you know it is receiving power from the car and your normal charging screen will appear on your iProduct. To set the cord length, all that’s required is a type of “pull and release” motion to get it where you like it. That’s it. Normal charging times apply and the length of the cord will still let you use your iProduct no problem.

A minor gripe includes the quality of construction in that I’m just not that sure how long it will last. The main body is made of two pieces of plastic that could possibly see the glue holding them together crack if dropped a couple times. Other than that I could envision a child totally yanking the cord past its spring loading but that again is a considerable longshot.

Contrary to the review on Amazon, the reCoil charges my iPhone 3G just fine. If you are looking for a one piece charging solution for for your car and iProduct I suggest checking out the Scosche reCoil. It’s easy to use, compact, and is on the cheaper side.

eWoo eFizz Travel Speaker For iPod Review

While iPod speakers are a dime a dozen these days, it’s often hard to find a really good one for the money. Ewoo, while sounding like an overseas car manufacturer actually makes a travel speaker dock for the iPod called the eFizz Travel.

Boasting up to 20 hours of wireless battery charge, the eWoo eFizz is an ideal companion when the scenario calls for no electrical outlets. Featuring an attractive all black finish the eFizz is head to toe speaker grill. Being one of the smallest iPod speaker docks I have used it is fairly lightweight and easy to hold. My iPod Classic 80g fit very snug and secure and the eFizz had a very cushioned and balanced posture sitting upon any level surface.

Operation was pretty simple overall. Colored lights denoted what was going on with the rechargable lithium-polymer battery and the remote while very basic, performed well. One of the touted features though, the “One Touch Info Button” did not work whatsoever. The user manual CD was vague at best and the email I sent two weeks ago to customer service has yet to be replied to. What it is supposed to be is some on screen iPod interface that shows battery level and some other things but I could never get to it. Not that it was a truly imperative feature it would have been nice to explore all of the eFizz’s offerings. Note: I did actually see this screen twice for a couple seconds at a time. It was totally random and I could not get back to it. All it displayed was the level of charge for the eFizz.

The eFizz connects easily with iTunes via supplied USB cable which is cool if you have it near your computer for transferring music or downloading new firmware. Note that you need to have power supplied to the eFizz in order for it to sync to iTunes. Though the eFizz has no real body controls to speak of, it’s easy to scroll through the actual iPod as it sits in the dock. What I would like to see most of these travel docks are storage areas for the remote and power cord so there’s not so many loose pieces. Also of note is that while wireless, the eFizz will not charge your iPod.

Sound wise I was’nt super impressed. The max volume wasn’t all that loud and the speakers were a bit tinny. Not that they were bad, they just sounded really small, because they are. At low volumes everything sounded fine as long as it didn’t have to compete with any extraneous noise. There was a bit of volume muffling that wasn’t totally distracting but noticeable to say the least. By my bed I did enjoy the low volume as everything sounded clear and crisp.

What will make the eWoo eFizz Travel stand out amongst the hundreds of speaker docks will be its wireless capabilities, long battery charge, and extreme portability. While the sound won’t blow you away, it will be best heard at small gatherings and picnics, or by your bed. FYI, the iPig is still the loudest and best sounding speaker dock I have heard yet.

Pros:

* Very small and compact
* Wireless with extra long battery life
* Syncs with iTunes

Cons:

* Sound could be better given price
* Poor customer service “One Touch Info Button”
* Sporadic volume muffling

World Cup 2010 To Bring Mobile TV To The ForeFront?

While currently no one really cares about mobile (cellular) TV, corporate executives are banking on World Cup 2010 in South Africa to finally bring the service some decent limelight. It really makes sense actually because the majority of soccer and World Cup fans will be working multiple jobs and will unlikely be in sports bars watching the games. I would think that we’ll see much hype behind this event as it approaches as well as some World Cup bundles and deals for current and emerging cell phones. What do you think?
