The Motorola Atrix 4G smart phone and optional Lapdock may have been too underpowered and high-priced to achieve true commercial success this year, but the combination gave us a glimpse of where the future of computing is headed. The Atrix functions as a standard yet powerful smart phone on its own but can be docked into the $300 Lapdock for a more traditional, laptop-style computing experience, with a full Web browser. It's a sneak peek at the days ahead when our phones become our only computers, hopping from laptop docks to desktop docks to in-car docks and everything else in between.
