SImilar issues here... I was wondering if the new screen lamination technology might be causing some of the unresponsiveness to touch.
I'm using iPad Air 2 with iOS 8.1... only had it a week now... Safari is buggy ...sometimes hangs up, sometimes slow ...forget trying to load a pdf document ...the page goes gray and both the "open in iBooks" and "open in" links do nothing.
I was a die hard hold out from converting to Apple products for years ...I used to joke about other people going over to the dark side because they switched to Apple ...along came the iPhone and I was hooked! I now own MANY Apple products ...I'm a total convert ...phones, tablets, home computers, routers, ...on and on ...exclusively Apple ...however... in the short time since Steve Jobs relinquished the helm, I have been left wondering about what seems to me to be a drop in the quality of the user experience with Apple products ...I haven't jumped ship ...not about to yet ...but I surely am concerned that they may be going the way so many good things do ...never to be seen again...
