I don't get the "regular Android updates" argument.
As per every Nexus phone, they're the first to get updates but they're usually just small updates that don't do very much. I.e, the Nexus S launched with Gingerbread and is still running Gingerbread.
When it comes to the next version of Android, the Galaxy Nexus won't be the first to get it most likely as if history is to go by, it will be launched with a new handset.
The Nexus One took quite a while to get Gingerbread as well, so it's not like the previous Nexus gets it that fast. So When Jelly Bean (or what ever they're going to call it) launches, the Galaxy Nexus may suffer the same fate.
So in my opinion, whilst Android 4.0 looks great and is probably one of the best features of this phone, I don't think having ICS for about 3 months before anyone else is that big a selling point. The other two main features aren't that great either.
- NFC - Pointless in the UK pretty much
- Screen - whilst lovely, pushing that resolution on such a GPU isn't going to do wonders for this phones gaming performance
Think I'm pretty much sticking with my Galaxy SII as once that has Android 4.0, it will pretty much be better than the Galaxy Nexus apart from the screen and it's not like the screen on the Galaxy SII is poor.
I don't mind TouchWiz either, hopefully the CM team manage to understand more about the GSII before the ICS source drops and that leads to better AOSP ROMs for the GSII.
