I had several ipads over the years and while they have problems, most are fairly trivial.
Most can be fixed with a shutdown and restart.
If you "jailbreak" good luck to you.
I've had two issues on both an iPad3 and a Mini2 on iOS7.
One was dodgy camera, appeared on both units. A factory reset worked for both.
Second was random Safari crashes. Only, in my experience happens on Mini2.
