Just now saw this...I just posted above about this phone. Have you heard anything about it? I'm thinking about it too.
CNet calls it the best Android phone currently out there. It certainly has superior specs to anything else. But I'm a little concerned about the battery life. Everyone who has the Galaxy Nexus says its battery life is awful. The Nexus has a 1850 mAh battery (I think) and the s3 has a 2100. If I can just the same battery life as my Droid X (1500 mAh) I'll be happy.
Something else to consider- the Razr HD is supposed to be coming out any day now. It will supposedly have the same big battery as the Razr Maxx, but with a faster chip, more memory, better display, better camera, etc. Might be worth waiting for.
