As a home user, I would not touch Dell with a bargepole.
Where I used to work, with lots of techies talking to Dell techies, we all had Dells and they worked fine.
I bought one for myself. It went wrong. It went wrong after about 72 hours. Hours on the phone to somewhere in the sub-continent, and hours of hearing the same script. They didn't ever bother to read the e-mails about the problem on file.
Probably the worst customer service ever. Worse than BT and British gas pre-privatisation.
Eventually persuaded them that new box was needed. They sent new one - which had less USB connections, and which made noises like a tractor.
Eventually got a friend to speak to Dell UK's MD, who very very reluctantly (after threats of Court case with him personally named) refunded my money.
Never, ever again.
