I was exited when they were working on Night Shift which helps with sleep, as I use Flux on my computers and its really good and the fact that there is no iOS apps unless you jail break the device.

I installed the 9.3 update within 3 minutes on my iPad Mini 1, iPhone 5c and iPod Touch 5th Gen, spent a few minutes trying to find the setting then boom looking online it's not compatible only by one model up! Due to hardware requirements apparently but honestly, I thought Apple was working at getting functionality across more current devices on iOS9.
