2. Haven't been watching any movies on the 2006 OS. Seems video doesn't work very well when playing long movies. I'm sure they will resolve this when it officially released. But you can finish a movie with a full charge.
3. Ever since I upgraded my 2006 it has shorten my battery life. Actually in a good way though...cause I use it more often now Web experience is faster and since it's new OS you tend to play with it more testing out different features. It use to be I can go on a day or two without charging, now I recharge it daily.
