Count me in for the SGS3. I was all psyched to get the HTC Incredible 4g coming from an iphone 4s (and loving the 3.5" screen). I don't like looking like i'm holding up a tablet to my face. But i am one who still has unlimited on Verizon and I've read they are changing over to the new plans this month.
Not knowing the release of the Inc and knowing that i can preorder the SGS3 on Wednesday is a done deal. If i hold out for the Inc and then it is going to release after the switch over i'm screwed. Plus if i wait and then want the SGS3 and try to order it, it will most likely be a long backorder.
So Con for SGS3: Huge stupid screen.
Plusses for SGS3: Same 28nm S4 chip as Inc.
EXCELLENT battery life (look at real world playback tests, beats X One handily).
2gb of ram instead of 1gb (might as well future proof)
32gb of internal space instead of 8gb (more space is always better)
I mean you all can do the comparison on phonearena or wherever. The phones are similar. You just choose huge (4.8) or just right (4.0) and touchwiz or sense.
I'm just going with the sure bet, which is SGS3 now and i'll get used to the huge form factor (though it is thinner than Inc 4g and has less of a bezel). All i need is a verizon lte phone to keep my unlimited and these are pretty much the only choices if you are looking to future proof your 2yr contract purchase
Good luck with the Inc 4g.
