I don't think you can get a better deal than this for a new device. At much as I dislike AT&T's customer service practices or their crummy network in my area (who am I kidding, their crummy coverage in general), this Atrix 2 deal on Amazon is awesome.
So far, the big thing about the A2 is its screen and faster chip. And honestly, what more can you ask for?
And remember how I was crowing about just how Android can differentiate itself from the tablets and really has been in the post-PC era? Get the Atrix 2 and a Lapdock and you're there!
