iOS 7 was pretty buggy - and I still had oddities on my iPhone 5s, before ditching iOS (for now, since I have app work I have to do on Windows Phone) and giving it to my wife. I haven't updated to iOS 8, because ... why exactly? Our iMac doesn't support any of the cool continuity features with our iOS devices, and they all seem to be running okay. Why deal with the hassle? Until apps that we use start demanding an upgrade, I don't think we will. Leave well enough alone, is my motto these days with iOS.
I do feel like some focus is missing at Apple ever since Tim started running the show. That infamous laser focus seems to be gone. They may be more profitable than ever, but at some point I wonder if Apple is now the digital equivalent of their Beats headphones. More a fashion accessory to have the gold plated Apple logo, than anything truly ... insanely ... great. Bigger iPhones, and a so..so..watch. We'll have some new iPads with fingerprint sensors this year as well. Some refreshed iMacs. All slow evolutionary changes. I have to admit, even Android which I hate is starting to look pretty good in many ways. I love my Windows Phone, minus the app situation.
I used to admire Apple products ... that "insanely great" thing about them. That sheen seems to be missing.
