Today is iOS 9 release day – which means that most likely, most of you have already upgraded. The Ars review concludes:
Last year we said that iOS 8 felt like the second half of the iOS 7 update, the one that completed the transition between iOS’ skeuomorphic era and our current reality, where the lines between “mobile device” and “computer” blur a little more every day. iOS 9 takes that foundation and builds on top of it without radically altering things, much in the same way that iOS 6 built on top of the advancements in iOS 4 and iOS 5.
It was a smaller release, and as a result, testing the final build of iOS 9 was frankly kind of a relief.
