I've really been impressed with HP's recent desktops, and I actually mean their Pavilion line. I wouldn't have said that a few years ago, but they've become competetive in price, quality, and features.
I'm still a little leery of their laptops, though. If I was spending my own money, I'd probably look between Dell, and possibly Sager. Toshiba's not bad either, but they can be pricey, and I've had the best notebook support through Dell. My work laptop (a once top-of-the-line Latitude C840) is about three years old now and has been wholly reliable. The only reasons I wouldn't get Dell now aren't reliability, but pickiness. They've mostly done away with the Trackpoint eraser-head mouse, my personal choice, and they no longer make models where you can have the CD-ROM, floppy, and battery in at the same time (yes, I still need floppy disks, I work in education where they can still be highly useful).
Why Sager? Well, they offer a huge selection of features/options, and they make laptops for a lot of other big names. They have some of the more powerful laptops on the market.
Then again, a fellow tech at a nearby school loves his HP laptop, and he's someone I trust.
