My friend has a inspiron and when he came to my LAN party with it he wasn't able to connect to my network, i tried everything! Oh and its sux balls when playing HL2 Deathmatch and was a lil buggy playing singleplayer. my friend has a Dell xps and loves it, it works perfectly. my other friend has some kind of Vaio and it runs HL2( and deathmatch) perfectly, although i hate Sony(personal reasons).
