Alright, here is my 2 cents:
I've never been an Apple Fanboy, but since I bought my first iPad (2), I can't live without it anymore ;-)
Said iPad2 was absolutely without problems, be it hardware or software. I just loved it and finally "got" why Apple has its followers.
The next one was a 3rd Gen. and sometimes "strange things" happened using the AppStore. Not too bad, just found workarounds and carried on. But I started thinking ... how hard can it be to make things work properly in a closed system?
But only since I bought my iPad Air (LTE/128GB), the problems really started.
I have the very same resets that are discussed in this thread. I tried setting up as new and other stuff mentioned here before and nothing did help.
The Appstore has a LOT of issues now. For instance, if I d/l an App and close the AppStore without closing the App's window first, it will become "un-closeable" the next time I start AppStore. Only killing the App and restarting it fixes this until the next time.
Overall, iOS7 is a great example of BAD BAD BAD DESIGN in almost every way !!
Johnny Ive, either you are getting old and tired or you never were the glorified designer you were supposed to be. There are SO many flaws, technical and regarding usability, a Kindergardener could not have done a worse job.
As for the reset-issue at hand, It happens to me about every other day. And so I just "live with it".
I have no confidence whatsoever that Apple would move a finger to solve this.
They seem awfully self-pleased and don't seem to even recognize that there ARE problems ...
Edit: Just wanted to make clear, that I never tampered with any device in any way. No Jailbraking or stuff, all 100% ledgit.
