Because of the performance drop, I had bought an iPad mini 4. After half a year I sold it because I simply didn’t use it often. I cannot imagine spending $400 on a new iPad. I will keep using my iPad 3 until it breaks. And I will not buy a new iPad again. The OS and form factor is too limited to do any serious work on it. (I’m not going to buy a keyboard and stand for a tablet just to have a subpar laptop experience.)
