Okay you have few options here
You can spend a lot of money and get the Dell XPS M1210,
or the Sony VGN-SZ430N/B both labtops are great, and they have good graphic cards, but they are very expensive. If you have enought money saved, then I recommend buying one of them.
If you dont', then you are looking at these models
HP Pavilion tx1000z, which is like a tablet pc, but it has a lot of futures built in, but it lacks of a good video card other wise it is a good solid system if you are not planning to play the new games that demand more from your video card.
or you can check the dv2000t it is also an hp product that has a lot of futures built in, but again lacks of a solid graphic card.
Good Luck
