I dont have one personally, but my neighbor has one and brigs it over alot to LAN with me and my brother.
Its a nice computer, but he got an early one (didnt ask me before he bought it) and got a 32MB FX5200..... sigh... Gaming isnt great because of the graphics card but otherwise its a nice system. VERY heavy and VERY big and bulky, but an awsome DVD monster. He says the battery life pretty much sucks, but what do you expect. Overall CS runs fine, but playing CoD, even at mdeium resolutions had trouble. Because LCD screens dont look '100% good out of their native resolution' he actually commented when playing side by side 2 feet away from my brother that his 15" monitor with 1.4ghz P4 and GF2 Ultra looked better..... lol
If you can get one of these laptops with a better graphics card it will make a nice desktop replacement machine. Otherwise i wouldnt get one. I personally went for a dell centrino with a R8600 pro.
