Q: 8.0 upgrade

Since downloading the upgrade, my iPad has crahed 7 times while trying to open the ABC app; it has crashed randomly upon opening; it has crashed in the middle of an Angry Birds game so many times I cannot count. I had very few issues before, certainly not enough to warrant writing to Apple about. I firmly believe this upgrade wasn't tested enough and should have been delegated to the iPhone 6 and 6.5 only. To foist this on the rest of us is callous and cruel. I didn't need an upgrade and, from whatI have read this morning, neither did anyone else.

If all the Apple geeks have to do is constantly work on upgrades, then perhaps you need to be more in touch with the average user who will tell you that your energies are being wasted. My iPad worked well before the upgrade. Now it works like crap. I cannot get my browser to open anymore without going through a ritual that includes a lot of backspacing, erasing, clicking off of "X" and backspacing once again. You guys have too much time on your hands.

Now, my question is this. How can I delete this crappy upgrade and go back to 7.0?
