I would say yes. I have had mine Since April 2011. If your not concerned about having an older OS, then its a good buy. If you want the most current OS, this isn't the phone for you.
Edited: I also, have the Lapdock and Standard dock. (I love the Lapdock.) Just these two docks alone add to the functionality of the phone. The Lapdock turns the Atrix into a netbook. The standard dock turns the Atrix into an alarm clock + docking/media station.
