Well, I do now swear by my Macs.
I find Dell, at work, very good for customer service (given that we're a large government authority with a Dell contract, though I understand they're not fantastic with home users) and they rarely go wrong, and the newer models of Optiplex PCs and Latitude laptops are looking nicer and nicer, though I've never liked a lot of the personal laptops.
Other than that our home PC is Advent (made by PC World), which is three years old and has only once had anything wrong with it - a hard disk failure. Luckily we got it repaired for free by the people I used to work for. I know PC World don't have much of a good reputation for PCs but mine seems to have been fine! xD
Otherwise, yes, I suppose HP like everyone else has said, although I still don't like pretty much any laptop designs outside Apple. I don't know why.
