Well, I'm a Dell Lover!
When I got it, the comparision price of buillding my own to the same spec was like twice. OK, they aren't the best in the world, but I've never has any trouble with mine (3 years old), so never had to ring the help desk
On a budget live in England, I bought my husband an Emachines for Christmas last year. In June it blew up. They sent a carrier to pick it up, and drop off a new one. It had Linux on, so I installed windows. It crashed repeatedly. I rang and told them. They came and picked it up, and credited my card for the bill for the computer. So... I got a computer for 8 months free!
So, now he's got an HP.
But, my Dell carries on!
