yeah, also on reading divx movies demand a lot less power due to non use of hardware such as laser on dvd etc.
It would be good to get 6 hours of movies, that will give you 3 of your own choice. I got an 11.5 hour coming up real soon and panic bought rather than be stuck on a seat with no player!, but I am happy that this is going to be the best netbook, most reviews rate it over the asus 1000H which was the only contender.
Also been looking at seatguru.com and seating and power supplies, some have empower some have ac power some have none! also charging iphone or mobile from it too is handy!
