Tell me about how you attach a file to the email. Or how you use the share sheet to interconnect apps.Nostalgia this is not. I have an iPhone 5 running iOS 6 and I can honestly tell you with the exception of today's additional features which are a given when compared to a five year old OS, it is a far more fluid, polished, snappy and enjoyable experience. And this is comparing it to the latest iPhone. It doesn't have micro stutters or lag everywhere and it doesn't have a poorly implemented, ameteur-level UI. Everyone has just forgotten how good it really was back then because we've become accustomed to the s**t show sloppyness that we have today.
Complexity comes with a higher risk of bugs. Still, iOS 9 onwards convinced me that the iPad can actually be a productivity machine. I’d always choose it over the polished-however-useless-for-a-power-user Forstall’s vision for iOS.
