Trying to decide if I should buy one. But I'm wondering what was actually upgraded from the last iPad. As I understand it: - Thinner and lighter - iPhone 5S processor (not A7X) - M7 coprocessor (I'm not really sure how this would be useful on a tablet) And maybe they upgraded the Wi-Fi? But then again that doesn't really matter because even if you had 500 gigabit Wi-Fi the bottleneck is still your internet speed. I hope I missed something. Or if this is it was the iPad presentation like 5 minutes long? Thanks!
