As I responded to someone's tweets last night and have said in a couple threads here, the 1GB in the Atrix is highly over-rated. That beast has a "docking application" (aka a 2nd pure Linux OS) running in the background for that docking station / netbook accessory. In the end the Bionic will have more memory available for applications.
This is the exact reason I come to these forums. Great information like this. That definitely made me feel better about the RAM situation. Looking forward to this phone even more now if that was possible.
