I use since a few weeks the Acer Travelmate 800 with Centrino and am very satisfied. This notebook can go forever without recharging plus its quiet and looks **** good.

Dont ask me any technical details of the speed but my computer-guru brother looked into all the available benchmark tests and according to him its pretty good (he just said "can I borrow it for the next lan party....your notebook is better than my pc).
