I have just installed it on my first gen 12.9 and it's running great! I had trouble with a third party app (Accounts 2) and DirecTV Now crashing. A reinstall of DTV Now and a hard reset fixed it but Accounts 2 still crashes every time. Otherwise, it is giving me no problems. It really, really does elevate the overall user experience and has given great new life to my 12.9! I also have a 10.5 but now thinking of returning it and keeping my 12.9 since it feels like a new machine now. I swear (maybe placebo effect) but it feels much faster and smoother to scroll and use overall.I am a developer but I usually wait for final releases. I am very curious about iOS11. On iPad 12.9 1st gen is latest beta stable or still giving problems? Do you suggest to install it or not?
I do it in my spare time. It's not my core business. Around 2009-11 I was very active and obviously I had to update with betas, but actually I am working very slowly.You’re a developer? An iOS developer with an app on the store? And you usually wait till finals unless you’re personally curious? Hmm.
