The wife has a 4 and I have a 4S. She's due for an upgrade, but I have to wait until Thanksgiving. We'll probably both be getting one of these two once my deal is up (we just got married so we still have separate accounts until my deal is up). I'm not all that picky about this stuff, but at this point, I'd rather stick with what is familiar. I'm glad I have to wait until November though, the initial rush to buy these things is always so stupid.
How much difference is there between the two new models? I haven't seen any of the descriptions yet, other than the finger print thing. I know I could just google it, but someone here will probably do a much better job of summing it up in terms that aren't way over my head.
