Just great. If I were to purchase the air 2, I would once again hold on to the stock version of ios as long as possible. I received my iPad 3 on launch day and I believe only performed one or two iOS updates since. Safari still runs great. I'll get an occasional crash here or there but it's been manageable and still very quick. AirPlay still works great with my klipsch speaker or apple tv. Battery life has held up reasonably well I'm still at about an 8-9hour avg on wifi. Verizon lte is still working great. I've lost some app support but not on any that I would miss. Watch espn still functions perfectly as does Netflix, amazon prime and logmein. Photo stream is also working fine as is Skype. FaceTime has issues but I use my iPhone, iPad mini or mbp to deal with that. Any other hold outs want to share their experience? Any one taking the plunge to 8.1 with their iPad 3?
