Warranty advice

[ghostface]

I always hated warranties and felt that they were a waste of money. Today though I was using a friends computer and it shut off and wouldnt start back up correctly. We got someone to come look at it and they determined the the motherboard had failed. It is a Gateway that is no more than 6 months old.

I guess I'm just wondering if a failure like this is a common thing. My new Dell just came in the mail and I havent even set it up yet and I am wondering if I should try to get at least a 1 yr warranty on it incase something fails like what happened today.
