Asus EEE: Had to pay for shipping of my netbook to get the dead hard drive replaced
Perhaps its too low ended of a "laptop" for them to cover the shipping costs.
Dell XPS m1210: Sent me box before 9AM one day after I talked to tech support about my dead video card problem, all shipping costs paid by them (However, I had to e-mail customer care, as the regular tech support people were unwilling to cover it because I was one year over warranty period).
