@ the OP
I see your using an Atrix... Which honestly I enjoyed owning! I loved the form factor...Awesome to say the least.
The GNex is fairly silmilar with the round edges...Much bigger of course, but similar.
Honestly, I could get into all the pro's and con's...But I'll make it simple for you...
The Galaxy Nexus is the Best Phone I have ever owned, and I've owned countless Android phones over the last couple of years...But if I had to answer the question as to which has been my favorite, the Galaxy Nexus takes the cake.
Just pull the trigger and get it if your funds allow it...It's pure Google, and your Future Proof for a while being that updates will come directly from Google. I'm hooked on the Nexus Line and will most likely not go back to using a phone that has a skin on it with an overlay built into the OS.... Stock Vanilla or bust is my feeling!
