As an Apple Developer and Huge Apple stockholder, it pains me to acknowledge this trend. The article below is not mine but the experience of a loyal Apple family. This makes me glad to be NOT updating my 2 old MacBook Pros, NOT updating my 3 year old iPhone 5 & 5S (yes I carry two iPhones) and NOT updating my 2 iPad3 and NOT updating one of my iPad Airs. I did update my other iPad Air and it has been a big PIA to get up to speed with corrupted passwords to email accounts and slow to update apps.
