I have two Dell laptops, one a 17 inspiron and the other a 14 latitude....both have functioned flawlessly for three years now. I had an HP laptop and the screen died right after warranty and the macbook my wife uses has started to crack in certain areas after a year and a half....still works though.

I also have a thinkpad that's 7-8 years old and the sucker is bombproof. Running Ubuntu on it now.
