It runs Android 2.2, with HTML5 support, and is AT&T's first dual-core processor in an Android phone. And it docks into a laptop. They're calling it the world's most powerful smartphone. ORLY?
It also has 1GB RAM, a 1900mAh (that's ginormous) battery, and 2x faster than competing web browsers. You can "view HD video".
Also! There's a Motorola Atrix Webtop Application, which docks your phone into a laptop, using it to power the entire laptop. This is like Palm's Foleo idea, but, you know, maybe not crappy. Firefox browser inside, running on this device, using the desktop version.
In short, the Motorola HD Dock, the thing that hooks the Atrix to a laptop, is going to let you use your phone as a laptop, taking advantage of the keyboard and mouse on the laptop. Still wondering about the employment of android 2.2 instead of something more contemporary, though!
