I also have had great experiences with dell.
Instance one. I completely nuked our dell about 5 years ago (was a computer AOL newb HAHA). These poor people spent about 2 straight weeks on teh phone wiht me fixing it for free.
Instance two. Sound card in my brothers computer went out. They had a tech out the next day installing a new one. Impressive considering we live in the middle of nowhere.
Instance three. Two and a half years into my three year warranty my CDRom starts to die due to overuse

Dell has a new drive in the mail the next day with a box for me to send the old one back in.
I have always been very, very pleased with all interactions I have had with them, and reccomend them to anyone looking to buy a computer that will come with great support.
