iPad Any one facing iPad3 slow downs?

I have an iPad 2/3 and Air. The iPad 3 is still running iOS 5.1.1 (no slowdowns) so can't help you there but yes there is a speed improvement going from the iPad 2 to the Air (7.1.2). Animations are smoother, apps open quicker, page loads are quicker. If you have an inkling on upgrading my suggestion is to wait for the refresh in the next few months.

My iPad3 is becoming more glitchy by the day.

I've now ditched it for a MBP, but the iPad will be going to my son. I'm intrigued to see whether we should keep it on iOS7 for him or put 8 on when it's out....

My iPad3 is fine. Even with jail breaking. Then again I don't do anything performance intensive with the iPad. Just ebook, browsing, light gaming and reading newspapers.

It's fine for the next year or so then I will upgrade. (maybe).

I did jailbreak it though to get the blur effects enabled, but i noticed with the parallax enabled blur hack that the battery drained a bit quicker then usual (that is obviously the graphic issue with the iPad 3s not able to handle the blur enabled effects like the iPad air and iPad mini/mini retina) so i removed the hack. Battery is much better now.

My 3 still seems fine and I play games. there are a couple apps that lag a bit but over all it's still pretty smooth. And I use the heck out of it.
