After many fails in areas like battery life, Game Center, App Compatibility, crashing, etc., I decided to revert to iOS8. I simply can't function at this point with iOS9, and unfortunately I can't afford to buy a second test device.
But, despite all of that, just minutes after getting a functional iOS8 reinstall and restore, I am tempted by the Siren call to put iOS9 back on. LoL Yes, the improvements, in my mind, are THAT great. Especially on the new iPad Air 2 I had to get to replace my iPad2. Just phenomenal.
So, a note to those who are on the fence about installing the beta, I don't personally think it is daily driver ready, and it will **** your soul like a banshee if you do it, but you will have a hard time ignoring the siren call once you have used it. 🙂
