Does that mean if you do the upgrade the iPad/mini won't work at all, that it'll be super slow, or that it'll only have issues with certain applications? I've bought iPad minis for all 5 of my grandkids. Three have the mini 2s and the 2 youngest have original minis. The 2 that still have original minis are babies/toddlers and the minis are pretty much just used in the car to watch Mickey Mouse episodes which have been downloaded to them, or really simple Fisher Price baby apps. At what point will the original minis be affected to where they won't even do this? Do I keep downloading updates? Do I ignore that? What is the best way to handle this so they can continue to watch the videos and maybe a simple app or two? I do plan to upgrade the older kids over the next year or so to mini 4s (or 5s if that should happen), so the little ones would get hand-me-down 2s at that point, but I want to be sure they'll be okay a while longer.
