I upgraded to the mini, and if that hadn't have been released I would have bought the 4th gen. I didn't need to replace it, and it actually did everything that i needed it to. However there were two things about it that really frustrated me. First, it wasn't upgradable to the newest iOS version, which made it feel obsolete. Second and this was the bigger reason if I'm honest, the keyboard was laggy. It would remember what I had typed, but would often be a word or two behind, which would end the flow of typing which is seriously frustrating. So I had decided to upgrade when new iPads came out.
