The one I'm actually most pleased with is an Acer. Granted, that's partly because it's a gaming laptop, but it's also both a good price and hasn't, y'know, exploded or anything. Previous laptops included a refurbished Compaq which has a problem somewhere in the sound connection (more likely attributable to the fact that it's refurbished) and, way back in the day, a Fujitsu that served me very well for many a year.
I currently also have a Dell work laptop. I've never been a big fan of Dell personally, but if you're not looking for gaming, they're fairly good price. My favorite professor also loves them, because they do have a fairly nice support system--they'll do things like remote desktop into your computer to fix it if need be, and they're fairly easy to upgrade hard drives and the like.
I have a soft spot in my heart for HPs, but they do have a habit of loading all sorts of unnecessary stuff on the machine and they're quite expensive. I'm heartened by their new dedication to actually producing and supporting their machines, though. Still, I had two desktops from them die within two years, so you can take that into consideration.
Dell-meh, not bad
HP - ehhhhh
Fujitsu - was fantastic a decade ago, I'll give it that!
