I have updated to iOS 10, and so far, I'm really not impressed, since it brings so few features that I care about that work on my iPhone 6 and in my region.
About a month ago, I discovered Apple had imposed new limitations on the free Apple Developer account. This limits the period that an app can run on your phone to 7 days (due to Provisioning Profiles) and the number of changes you can make to the project (not the source code, but Capabilities like App Groups).
I just bought a MacBook Pro! Prior to this, I've only been exposed to Windows and a smattering of UNIX/Linux... until now. What really struck me was the price! Total sticker shock, and that was before Apple raised prices on 14 Oct 2015!
