I'm not super excited about this one, but I'm going to stop in a few stores on launch day and see if I can find a gold 64. For me the main reason is the camera upgrades and, specifically, the slow mo video. Will I use it much? I don't know. But that is the feature I'm more excited to see. I trust that the processor upgrade will make for a better experience day to day. I think the M7 shows promise for improving battery life, along with endless possibilities for apps. And although I wasn't interested in the Touch ID before the keynote, I think it's great. I will finally secure my device and I won't need to do anything but touch the home button to unlock my phone. I think all these things make for a pretty substantial change honestly. Going from my 32 gig 4 to the 64 gig 5 with LTE and a larger screen was probably bigger, but this is nothing to sneeze at. I chose not to go from 4 to 4S. I have an upgrade open on my account, so if I can find one, I figure I'll do it.
