i am really excited how good the web browser is now. So snappy and finally you can scroll a web page as fast as you can on your contact list. Also the new privacy features and that you can set the reader view on automatic for all sites who support it. So far everything seems to work fast. Not sure about the battery yet, the update took 25% of my battery. But my fears it would slow down the SE are gone. It feels much faster than on 10.
