The fact that Apple is releasing an iOS 8.1 version soon is not even closely related to the certainty of it being related to your problem. You can't assume that. There are some minor issues that the bulk of users are having, but they are not making the iPads unusable. Apple will be fixing those, you see, plus anything else that they can identify from specific problems submitted to Apple Support.
I've give you just one example of a minor problem with iOS 8 which does not affect things in a major way at all. There are some instances in which the software keyboard covers up the entry point of the screen. Sometimes you can just scoot it up higher and it will uncover it. At other times, the page isn't long enough to scoot it up and then you have to type without seeing it directly, That's an example of a software bug and a minor problem that Apple will fix with an update.
SO ... again ... just because you see Apple issuing an update, it doesn't mean that Apple has had a major problem that "makes my iPad unusable" (as some have said) and that they are "fixing that" (according to what people said). Apple may be simply fixing those issues like the keyboard covering up the entry point and other such things.
And, if you hear "that" ... you'll say, "But what about them making my iPad unusable?!" The fact of the matter is that Apple hasn't made your iPad unusable or cause it to fail in a major way, because if that was so ... then the entire installed user base would be unusable. It's not, and thus ... what is going on is that you have something that is peculair with "your particular setup" that is causing trouble. You have to diagnose it from that standpoint.
AND ... you can take encouragement from the FACT that the vast and overwhelming majority of the users in the installed user base is NOT having problems, because that means that it's just related to "your machine" and is THEREFORE "fixable" at your machine level!
