Being able to get rid of the notification alerts that hinder any functional progress on whatever it is you were doing before the pop-up came along is pretty nice.

Also, the notifications from the lock screen information view is very nice to have. From a usability standpoint being able to triage a sms or email ping sound with one button rather than:

- button click to end sleep,

- swipe to unlock,

- another button click to enter sms or email,

- (maybe) one last button click to open a message.
