I'm not sure what you think wireless charging is, but it doesn't allow you to charge the device from anywhere in the house or have it charge while you walk around with it. Wireless charging means putting your device on a charging mat that's plugged into a power outlet. It's wireless but not contactless.
If you're using a cable you actually can use the device while it charges. A charging mat, however, doesn't allow you to do that. It's appreciably worse as a charging solution in almost all ways. It's fancy and high tech but it serves almost no useful purpose.
As for NFC, fine. It's a nice bit of tech. Would have liked it but it's not a big deal.
12 megapixels? Why? How large due you want your photos to be? I'm always perplexed when people tout megapixels as a big deal. I thought we'd got passed that.
Because the fact that apple didn't even bother to update the camera from the 4s shows how either lazy they become, or cost oriented they are.
