Motorola just unveiled its powerhouse smartphone and were kind enough to have a few for us to play with. The Atrix 4G seems just like how Motorola advertises it: a desktop replacement smartphone. The phone was displayed alongside its dekstop dock that brings the entire smartphone experience through the eye’s of Motorola’s Webtop interface. Think OS X meets Android. There’s a dock at the bottom but the usual Android apps and functions.

The phone itself is hefty, solid, and feels a bit like the Evo 4G in terms of bulk. Not that its a bad thing, but it’s not a featherweight by any means.

We’re trying to figure how you’d use this and as a capable desktop replacement in a pinch it may be a winner. Like the iPad, you think you can get work done on it but with the full screen and keyboard you actually might be able to get some work done on it. The HDMI-out feature will probably be underutilized but as a laptop alternative it’s quite compelling.
