Re: Would it be worth upgrading to the S III from the Galaxy Nexu
It's coming out June 20 or 21 this month.
The S3 is Samsung's flagship phone for this year. Any new phones will be just the same thing with slightly bumped up specs and tweaks. The next nexus, whoever will be making it (Asus?) will either be just marginally better, or most likely equal in some respects and worst in others. The Galaxy Nexus wasn't that great compared to the S2 released six months earlier, with weaker cam, build, battery, processor, and other deficiencies. All it had going was ICS and 720p display, and 1080p displays aren't gonna pop up until next year (LG's panel won't even start shipping until later this year, which means it's for next year's crop) so 99% chance the next nexus will not have a 1080p panel.
I've been following all the top Androids and really, the best one so far is the S3. Doubly so for T-mobile, since you need the AWS band and the only top tier phone coming out for T-mobile in the foreseeable future is the S3. The HTC One X is an exclusive for AT&T for who knows how long, and other than the nice display, has some shortcomings. Same goes for the One S that's for T-mobile. The Optimus 4x, who knows if it will even come stateside.
