Mine froze like this once during initial set-up. While iTunes was transferring everything over, or at least attempting to, the iPad Air 2 just froze on the set-up screen. I had to do a hard-reset in order for it to start working again. I also had it crash once today, restarting to the Apple logo, while watching a video on YouTube. I'm coming from an iPad 3 and it was a long while before I had issues like this with that iPad. So, a brand new device displaying problems already is a bit disconcerting.
I hear you man. This is my first iPad so think how I'm feeling about it so far
