IOS 11 was slowing down my Mini 2 too much. Actually the slowdown started after I upgraded from IOS 9 to IOS 10 and it was annoying me too much. I hope I did not buy the new model right before they release the iPad Mini 5 but I doubt it. Anyone have this model and do you like it? How well does it run IOS 11? Mine is upgrading to IOS 11 as I type. One annoying thing about the 4 is that its only sold in 1 size. I would have taken the 32GB model but its only sold in 128GB. I have lived with 16GB for 4 years with the 2, how will I fill up 128GB's?
