So I went ahead and installed the #iOS10Beta yesterday, here are some nagging features..

1. I have press the home button to get to the homescreen, just the TouchID does not work #iOS10Beta
2. Quick reply feature in Notifications is missing (or I have not found it) #iOS10Beta
3. Notificaitons cannot be clubbed via applications #iOS10Beta
4. Not a fan of the Boxy notifications #iOS10Beta
5. I feel the active display will eat up a lot of battery #iOS10Beta
