Apple needs to have an appropriate response to the issues. Like everyone that has an iPad 2, I also have severe performance issues with iOS 8.0.2. While 8.0.2 did improve performance on my iPad and the other iPads I have tested it on, the performance does not come anywhere close to the performance of iOS 7.
The performance improvements of iOS 8.0.2 over iOS 8.0 are proof that the performance issues ARE correctable by Apple without the need to reload OS. As a computer geek by trade, I fully understand the expectation of some sacrifice in performance for the latest feature set. I also expect Apple (who have classically done this) to not allow products, that will not perform, to load the latest operating systems. Apple has done this with every one of their products, from the Apple TV to the Mac Pro systems.
I am sorry to say that I am disappointed with Apple on this release, and consider it to be quite the black eye.
