It supports microSD, you could have 48GB total. The "netbook" dock is also intriguing: I'm interested to know how much hardware is in the docks and whether or not the Atrix supports USB OTG "natively" (the docks have full-size USB ports but it's unclear if this is a feature only the docks can support). Additionally I hope someone makes a small/pocket-able slide out keyboard attachment for Atrix (BT would be fine) Furthermore it is unclear if Motorola will lock the bootloader (probably) and whether or not anyone can crack it. Additionally even cracked, the modifications required to make "vanilla" Android 2.3+ work with the "webtop" applications may prove to be quite a challenge. Unfortunately there are simply too many unknowns at this point. And AT&T isn't known to go easy on the "DRM".
