First impressions.
- Touch ID requires physically pushing the Home button now. Before, you just had to place finger on the button. Maybe there is some good reason for this, but I don't particularly like this. I often have my iPad in a stand with keyboard paired, and I'll have to counteract the force of pushing the button somehow to avoid destabilizing it. Or type my passcode in with keyboard.
- Quick Settings (swipe up from bottom) is split into two panels now. If you were trying to find the playback controls, you have to swipe over to that panel. Again I don't particularly like this but perhaps understanding will arrive that it is better somehow. Please don't tell me app developers can now add new widgets and panels that you have to swipe even more to get to 'quickly'.
- I've had it complain a couple of times about an 'incompatible accessory', and while it fails to specify any details, I assume it is my third-party USB cable (the Official Apple one is too short and flimsy), which right now is plugged into the pass-through Lightening port on a USB adapter (Apple's if the packaging was to be believed). It stopped charging, and only resumed after I unplugged the adapter from iPad and plugged it back in (there's nothing plugged into the adapter USB port at the moment). This never happened with iOS 9. Maybe it won't happen any more but if it does it is going to be very annoying.

Apparently our iPad 3 is not going to get this update. It's not clear why that is the case, but apart from potential for apps dropping support for iOS 9 that is perhaps not a bad thing.

I guess I need to go over the 'what's new' list again, maybe even review developer facing features to know what I'm missing. As it is, I'm not seeing any compelling reason to update.
