If the laptop just sits on a desk and you NEVER have a drink next to it and know you won't ever stick a pencil/pen above the keyboard and forgetfully, close the lid and crack the screen, then don't get the warranty. But, laptops are portable and people take them lots a places other than sitting on the desk. Also, especially for College kids and younger, get the warranty. Maybe you'll never need it, but laptops can't get knocked off desks, fall off a precarious perch, lap, table, whatever, and a majority of people I would bet, have an open can of soda, cup of coffee, or other beverage sitting next to the laptop when working on it.

For most products, I never advocate the extended warranty, but with laptops I always recommend it.
