Mine seems fine, iOS 8.1 has made mine a lot faster compared to iOS 8.0.2
The only stutter I get is rotation with the keyboard up. Safari seems pretty swift and stable.
Better battery life, 16hrs usage on last charge cycle.
Think this will be the last major iOS update i'll do to my ipad 4 though. Not prepared to spend a month using early slow buggy revisions again!
My iPad 4 is close to unusable with 8.1....
seems slower. ... anyone else think so ?
I'm wondering if the OS was designed knowing that the Air2 will have double the RAM.
