I agree. I dont think the 512mb ram is a HUGE issue like everyone is making it out to be... Think about these things:
1: The ATRIX has a 4in screen the BIONIC 4.3 (bigger doesnt always equal better, but this phone seems more like the EVO4g then the DX form factor)
WINNER - Depends, but the BIONIC is bigger :)
2: ATRIX has a out dated 5MP camera (probably a upgraded version from the D1 with HD recording..) BIONIC 8MP..
WINNER - The BIONIC has larger pixel count, and probably a newer/better sensor then the ATRIX. Bigger doesnt always mean better, but why would they only put a 5MP on the ATRIX???
3: ATRIX has 1g RAM. BIONIC has 512mb
WINNER - ATRIX.. but like someone else said, the atrix is essentially a dualboot system needing that extra ram
4: ATRIX has that docking thing, fingerprint reader.. blahblahblahblah
When I see all that all I think of is a developers nightmare. It will probably be so difficult to create roms that fully use the features of the phone, that it may be a neglected cousin of the BIONIC. Chances are that within months of release (providing the unlocked/easier hacked bootloader) the BIONIC will have custom roms with ported versions of all the 'good' features of the ATRIX like the firefox thing.
WINNER - BIONIC.. I see the BIONIC as the next D1, and the ATRIX seems to be geared towards buisness users and will be a pain to rom for without losing tons of features.
Thats just some of the differences that ive been thinking about, but I really dont think that the RAM issue (while annoying) wont be a issue, and the community will fully back the BIONIC....
Im buying the BIONIC no matter what :) locked down like the white house or not.. It looks like a fantastic phone.... and my antenna is broke in my D1 :(
