Smartphone and tablet announcements at Mobile World Congress
This week was full of high-profile tablet and smartphone announcements as consumer electronics manufacturers fought to dominate headlines during Mobile World Congress (MWC). Highlights included the 41MP Nokia 808 PureView smartphone, HTC’s One X with a quad-core processor and ImagesSense technology, the world’s fastest quad-core smartphone the Huawei Ascend D quad, Asus’ 3-in-one PadFone, and the Samsung Galaxy Beam with its built-in projector.

Windows 8 Consumer Preview

Microsoft launched the Consumer Preview edition of Windows 8, its next generation operating system. The beta preview — which is available for download now — offers a new touch-based user interface, support for the new Windows Store and Metro-styled apps, integrated cloud storage, and the consumer preview of Internet Explorer 10.

Apple’s March 7 press conference, iPad 3 rumors, Apple TV

Apple confirmed that it would host a press conference on March 7 at the Yerba Buena Center for the Arts in San Francisco where the company is expected to announce its next generation iPad, aka the iPad 3. Blogs have been posting a myriad of rumors surrounding the event and the next gen tablet. Most say the iPad 3 will ship with a higher resolution “retina” display, an enhanced processor and 4G connectivity while others suggest that Apple will also use the event to unveil an updated Apple TV. Additional rumors published later in the week hint at smaller and cheaper iPads.

Reviews of the groundbreaking light field camera Lytro

Lytro started shipping the world’s first light field camera to consumers in the US. Bloggers were given hands-on previews of the “living picture” device. They declared “it’s not hard to believe that Light Field technology is going to upend the way we take pictures,” “[i]t’s simultaneously addictive and frustrating” and ”The Lytro LFC is unlike any consumer camera we’ve ever seen before – it captures fundamentally different information and produces output unlike any conventional model.”

Facebook game maker Zynga launches

Facebook game maker Zynga has broken away from the clutches of the social networking site and has launched its own website and gaming platform. The shift means users can now play the company’s popular social games including CityVille, Words with Friends, CastleVille, Zynga Poker and Hidden Chronicle outside of the Facebook ecosystem. Third party game developers will also be able to publish their games on, the beta version of which will launch in early March.
