...personally, I think iOS 8 runs really buggy for me on my iPad 2 (now updated to iOS 8.0.2 - but issues still remain). I wish I had stuck to iOS7 if I am honest!
I updated via the OTA update.
The worst thing is, are the animations when zooming in and out of folders/apps. I rarely get a single smooth animation - they just constantly stutter, like the iPad is finding it really difficult to process the zoom!
It really is quite frustrating when I tap on a folder/app, and I have to sit there and wait/watch the stuttering animation go through the motions before the app/folder actually opens!
Even if I turn the animations off and instead use the 'fade' animation (instead of the 'zoom'), even that stutters!!
I also get blank icons for the bookmarks which I have added to the homescreen. The only way to get these to display correctly is to delete them and re-add them to the homescreen?!
Is there any way I can wipe my iPad and do a clean install of iOS 8, to see if it makes any difference to the stuttering/speed issues?
I found this with my OTA update as well. A restore using iTunes seemed to fix these issues, and while it was a bit slower than iOS 7, it was a lot better than iOS 8 OTA
The iPad 2 is still the most used iPad out there so Apple is bound to improve performance, and hopefully 8.1 will
