Just about every single component was changed or upgraded. So that's pretty big. In previous generations of iPhones they only focused on one or two parts. 3G/cellular improvement, 4/screen & design, 4S/speed & camera, 5/LTE cellular improvement, screen, design, cameras, dock connector. Definitely the biggest iPhone upgrade they've ever done. I don't know if wireless charging has improved since the Palm Pre days or not but it wasn't really setting the world on fire back then. NFC is pretty neat but my guess is Apple is looking at their own system they can control and profit from. If NFC becomes a big deal before they do their own system it may turn out to be a bad gamble.
