It's not about what happens to the laptop after the three years. The point of the warranty is to have reassurance in case sometimes goes wrong within three years.
He brings up a good point though... Yes, near the end of the warranty, odds are I won't really care... Its more about what happens within a year or 2. If it was $60 for 2 years, I'd be happy still. @ $60 for 3 years, even better. Hell at $60 for one year, I would think it would be considerable.
Warranties are for some people, not so much others. I have used a 3 year warranty on a computer once (near the third year)... it was a mac.
