Notebook's lag behind desktops about a year. And the end of a desktop for a user like myself is about three years before it gets just to slow, this is about 2 years for notebooks. So look at the 2 year plan. I have a 1 year old Inspiron with a 1 year warranty. As soon as the warranty was up i started having problems with the screen. Should've got a longer warranty!
Well I took the screen apart and found a point where if I applied a bit of pressure I could get the red lines to dissapear so i insert some folded sticky notes and put it back together only to find it bends the outside plastic slightly instead of the screen so know I have a metal bar and tie straps holding the monitor against something flat. Problem solved, at least when i'm at my desk...
