We are iDevice family, I tested out iOS 8 first then after all the bugs put a halt on upgrading the others. Bluetooth pairing issues and the home button bug are show stoppers until they are fixed. iOS 8 was not ready for prime time (at least for legacy devices).
really should keep signing previous versions of iOS longer so if upgraders deem the update to not be up to par for them or they experience mass problems to downgrade... I know, pipe dream but man if there is one thing I learned from updating to iOS8 8on the 17th is..... WAIT!!!!
