First Sight of Google Android
CorinneI writes "At the Mobile World Congress show, four mobile processor vendors demoed pre-production devices running versions of Google's Android OS — a Linux-based, open operating system for mobile phones that will sport Google applications. The biggest surprise of the demos was how well Android runs on slow devices. 'TI showed Android on a Motorola Q-like QWERTY handheld with its 200 Mhz OMAP 850 platform, where the user interface felt smooth and fast, even with little Apple-like animated transitions between screens.' HTC, Motorola, LG, and Samsung all belong to Google's Open Handset Alliance"
Just use Google!

"Android will be open source; it can be liberally extended to incorporate new cutting edge technologies as they emerge. The platform will continue to evolve as the developer community works together to build innovative mobile applications."
