We have 2 Ipad 2's. One is 16GB and the other is 32GB. I updated the 16GB to IOS 8.
Initially there were quite a few problems that I solved by reading suggestions from this forum.
I was impressed by the contributions and suggestions. I have used many and the Ipad 2
16GB is running much better but I had to move all of the Pics to my PC and remove some
APPS that seemed troublesome. There is no doubt that the Ipad 2 with IOS 8 is running slower
than the Ipad 2 with IOS 7 but the latter has more space 32GB vs 16GB on the unit
running IOS 8.
I think the Ipad 2 16GB unit will be limited with IOS 8 but can still function fine. We have
not used either with cellular since the change but will probably only use cellular on the
unit running IOS 7 and 32GB.
I am hopeful that Apple will make some more improvements to IOS 8 so that
both Ipads run smoothly. I do find it annoying looking at a white screen waiting for
email to open. Safari is not running as smoothly on IOS 8.
