I just got one of the HP DV9500's 17" screen 256 dedicated memory 2 GIG RAM 240 GIG HD 1.6 GIG Dual Core CPU. It get 4.5 vista score. I am very happy with it. It also comes with a TV tuner card with remote. I do not carry it anywhere so I can not say that it is something that would be fun to lug around a campus but it is a good solid machine. 1300 six months ago at best buy. I personally would stay away from Dell. I am an IT Manager for a decent sized Downtown company and we have had 4 major issues involing 100's of machines at a time. Good Luck
HP's are great machines, just make sure wherever you buy it from (i know best buy can do this) unloads all the pre-loaded software. Most HP's come with it (all that i have ever bought or seen people buy)
What problems do you guys have with dells (from a technical standpoint)? I have used many dells and except for obsolete machines never had a problem. Please pm me, i want to prepare for the worst haha.
