It is kind of pointless to warranty something that drops in value so fast. The only thing that has ever broken on the laptop's I have owned for the past 10 years are hard drives, and I prefer to upgrade rather than to replace with those anyways. Actually the hard drive in the powerbook 1400cs I own is still going..
I just got 1 year mail in and accidental damage. I'm taking it to trashcanistan with me and I consider it disposable, if it makes it home with me great, if not I'm sure I'll get my money's worth out of it. My HP that I took to Iraq with me actually made it home in one piece, but it is beat to holy hell. Now I just use it as a data logger for my truck.
On my sons 6000 for college we got the 2 year plus complete care. I had a 3 year when I got my 8100 a few years back and in the first two years I had to have the motherboard replaced three times. Glad I had the longer warranty.
