I'll have you know that a battery miser like myself can squeeze out a full two hours on a 9100.
I personally think my 9100 is better. It comes with a WUXGA as opposed to an XGA LCD, and the smaller screen is, for me, only a plus-17" is too big to fit in ANYTHING. It's more expensive, and the battery is smaller-I believe the stock one is only 6 cells, but even if it's 9 you still would'nt get terribly good battery life.. If it were'nt for the decent graphics card and enormous LCD, it does'nt have any features that make it better than the old 9100.
If you really need anything with an LCD this big, go for a Toshiba.
