Microsoft begins shipping early builds of Windows 8 to key OEMs

Tantalizing bits of Windows 8 have been revealed since June last year, and at CES 2011, Microsoft officially revealed the hardware agnostic nature of the upcoming platform, touting support for both ARM and x86 designs. Now, accompanying the latest leak of a Windows 8 System Reset feature, come reports that Microsoft has already begun shipping early builds of Windows 8 to key OEMs, such as HP. Related Stories Microsoft is supposedly distributing build 7971.0.110324-1900 (Windows 8 Milestone 3) through its Connect external testing system. The OEMs who have received this build are part of what is known as the Windows 8 and Server vNext Pre-Release program – companies that will help Microsoft test builds and offer feedback.Microsoft is expected to release a full-fledged beta of Windows 8 by September 2011, ahead of its release candidate and launch sometime in 2012. As for the System Reset feature, it looks to be a quick way for users to restore their device back to the original OEM settings, without re-installing the OS or re-formatting the HDD.

Indian Windows Phone 7 users can now access Zune Marketplace


Indian Windows Phone 7 users will be happy to note that the Zune Marketplace is now accessible to them, via the downloadable Zune App, though Microsoft has yet to officially announce this.
While different users have been enjoying varying levels of success accessing the Zune Marketplace for India, it seems for now only applications will be available, no Zune Pass music or video content. Those who already have a US-based Live ID, and have logged in with it on their Windows Phone 7 device, will face some trouble switching it to an India ID – and might have to hard reset it.

AMD releases Radeon HD 6790, its top-end mainstream GPU


AMD has released its cheapest retail HD 6000 series GPU today, the Radeon HD 6790, priced at $149, below the HD 6850. Presumably meant to take on the recently released GTX 550 Ti at the price, the Radeon HD 6790 actually takes on the GTX 460 768MB variant instead, as Nvidia has just slashed prices of the GTX 550 Ti by roughly $20, to $130.
For those of you wondering how the HD 6790 is the cheapest desktop HD 6000 series card, and if we aren’t forgetting about the HD 6770 and the HD 6750, note that those are actually rebadged HD 5700 series models only for OEMs.
The HD 6790 seems like AMD’s answer not just to Nvidia’s high-end mainstream competition, but also to its HD 6850 binning woes. The HD 6790 is based on the same design as the HD 6850, but has slightly faster clocks, half the ROPs, reduced texture units and stream processors. Unfortunately, as the HD 6850 was a salvaged GPU of the HD 6870, this makes the HD 6790 a “3rd tier” card in AnandTech’s words.
Just like the HD 5830 or the GTX 465 were in their series. Such cards, and the HD 6790 is apparently not an exception, have the power draw of the 1st tier or top-end card, but the lowliest performance of the series. Check out the comparative specs in the table below:

Continuing with the 3rd tier product lineup, it would have made sense to call the HD 6790 the HD 6830, filling up the HD 6800 series just like the HD 5830 did for the HD 5800 series. However, the HD 6790’s performance is much closer to the last generation HD 5770 than to the HD 5830, and this is probably the reason AMD placed it in the HD 6700 series.To be noted however, that the HD 5830 and its 3rd tier flaws were due to the fact it was a salvaged-salvaged top-end Cypress GPU (i.e., HD 5870). In the case of the HD 6790 however, it is a salvaged-salvaged HD 6870 or Barts GPU, and not AMD’s top-end Cayman lineup. This gives the HD 6790 a fighting chance in the performance vs power vs temperature battle.
While the reference HD 6790 used for early benchmarks had AMD’s efficient HD 6800 series cooler design onboard, no partner cards will feature that design, but instead, their own cooling solutions. Check out a Sapphire design below:

On the whole, most reviews feel that AMD has made one of the same mistakes with the HD 6790 that it made with the HD 5830 – it has priced it too at launch, compared to its 2nd tier part. So while the HD 6790 does significantly better than the now lower priced GTX 550 Ti, but, does not compare to the equally-priced GTX 460 768MB, or the just $10 more expensive HD 6850. This effectively leaves the HD 6790 in a peculiar segment of its own –catering to those looking to buy a card this very moment, with a un-stretchable budget $150.

Windows XP Still in 60% of World’s Computers

Figures from NetApplications are frequently rolled out regarding the major operating systems’ share of the market. The figures presented today tells us that it goes down for Windows on the whole; it’s up for Windows 7 but down for Vista and XP. The figures indicate that many Vista users have switched to another OS. Vista was apparently down 0.65% in September and landed at 13.65%.
XP is also declining, although very slowly. Microsoft’s operating sysyem, released nine years ago, is still in 60.03% of the computers in the world, down from 60.85%. It is now quite old but retains a good foothold, a foothold that we will see become increasingly weak as no XP computers are being produced and even more so when Microsoft gets rid of all the support for it in 2014.
Win 7 picked up a further 1.25 percentage points but failed to keep up with the Windows XP and Vista loss. In all, Windows lost a total of 0.25 points of the market. Exactly where this percentage has gone is unknown at this point. Both OS X and Linux are still at 5.03% and 0.85%. The only OS that has demonstrably gone up is Apple’s IOS which now has 1.18% of the market.
Its the time to think that wheather windows 8 replace XP

Motorola’s Latest Smartphone Powerful Enough to turn into a Laptop

Motorola launched its top model the Atrix 4G at the CES trade show in Las Vegas this January.The Atrix smartphone is one of the most impressive smartphones yet, with an Nvidia Tegra 2 processor, giving ample overall performance to run a Personal computer-like practical experience.For this function alone, Motorola has built an add-on termed the Lapdock that turns the smartphone into a laptop when you attach it to the again of the Lapdock:

Atrix in its dock
The idea right here is that the smartphone has enough performance to act as a notebook and by placing it in the Lapdock you will get exactly this. The thing that actually comes about is that the smartphone fires up up an application called Webtop, that powers the display of the Lapdock. The Lapdock has no separate OS; the Webtop app offers a PC-like FireFox browser including support for Flash.
As a result, you receive a relatively competent laptop that can do about the same stuff as small laptops. It is also possible to enjoy videos and do other stuff you would count on from a normal netbook. It performs as a decent small notebook, albeit not an overly powerful one. The device is fairly big, not drastically smaller sized than the normal netbook or ultraportable. It weighs just over 2lbs and is about 1.4 cm thick. The display is eleven inches and the resolution 1366 x 768 pixels, which seems to be the standard these days. The integrated battery will remain alive for 8 to 10 hrs of use. There are also stereo speakers included plus 2 USB ports.
Its keyboard is backlit and looks like those you see on Sony Vaio notebooks. It provides full size keys and an ergonomically correct operating posture for the Atrix Lapdock. Beneath the keyboard is a standard track pad to manage the mouse pointer on the screen. This one has support for multi touch so you can scroll down websites by dragging two fingers across it. The Wetop GUI looks a great deal like the Mac OS, with animated program icons at the bottom of the screen. It also has regular application windows that you’re used to from a normal computer. Another attribute is that even if the Atrix is attached on the back of the display you can nevertheless use it by way of an application termed mobile view.
This is only the display on your phone but with full accessibility to all functions. The Atrix and Lapdock are not powerful enough to replace your regular computer. However, it’s nonetheless an incredible idea that displays the capabilities of the Motorola Atrix and the Linux-powered Android operating system. Sadly the dock for the Atrix is rather pricey. It will cost far more than the Atrix itself. At some point Motorola will supply all of their best smartphones with the Webtop app, so it seems that the manufacturer has confidence in the idea and will carry on to build on it further.

Logitech HD Webcam C510




Up on the review block today I’ve got another HD webcam from Logitech, the C510. A little bit ago I looked at the C910, which is pretty much the top end camera, this C510 is more middle range offering 720P resolution. The resolution is lower but the features are the same like pan, tilt and zoom and numerous special effects. The C510 even includes a nice little carrying case so you can take it with you and keep it protected
