I should point out that with the OS update both of them gained improved features and are now equal in browsing and app support.
These are all cosmetic differences. The real diff are: Camera resolution: Atrix 2 wins, Storage: Atrix 4G Wins, No FM Radio on Atrix 4G but that kills battery life; Atrix 2 advantgege on wider screen. all else are gablish - not essential difference.
You are rite but when you need that quick snap for upload,  a good resolution camera could go a long way - snap and hit the upload button. I do that a lot and it makes a big difference though I have Canon XTi and a point and shoot. All can be handy for a specific task. 
 i think atrix 4g is better for me. that is why cameras are made and phones are made to be used as a phone and not a camera.
atrix 2 is a 21 meabit device !
Hey @gjacobellis:disqus  and @889d87e461d745062ad09b90d0008d3c:disqus , it looks like you are right, sorry about that. We will fix up our specs soon.
I don't think that the phone has an FM transmitter, I cant find anything about it anywhere else on the internet. This article may be incorrect.
Can someone explain to me how to play music through my car speakers through the FM transmitter with the Atrix 2?  Can't figure it out. :(
The atrix 2 DOES have hotspot capabilities
