How about things I wish it didn't do?
I can't believe I now have to worry about where I start to pulldown the notifications since there are two separate panels and the quick link to settings has moved over to the 2nd pulldown.
Why do so many user interface designers like the Chinese puzzle box model? NO! You can't put that there! Someone might find it!
On the good side, it installed OTA for me - I had to manually install 4.1.2.
Now I'm off to get rooted again...
