Once ICS comes to other phones on AT&T the Nexus will be no big deal. We saw it with the Nexus S. Once they finally got it out on AT&T, they had to practically give it away. I had one for about two weeks and it had nothing over my OG Atrix or even captivate, so I returned it. The HD screen cannot be that big of a deal since the LG Nitro is not selling well, of course the battery life on the phone probably has something to do with it.
I would like to have the option now to have a 32 GB version but once my SR get ICS, I would not consider the Galaxy Nexus.
