We've had a lot of different computers around the house: Timex, Commodore, Generic, Dell laptops and desktops and the Fujitsu; plus a variety of computers I've used over the years at school and places I've worked.
My favorite is the Fujitsu. It has lots of i/o ports (4 USB, firewire, IR, S video output, etc.), it's well built, a cool silver color and has a really handy little scroll button. The one I'm using is getting a little old with a 1 Ghz processor, but it's still quite functional. It's not ultra portable being around 7 pounds, with a short battery life and a little thick (like me)...but I really like it.
I will probably get the DC power jack repaired again (2 to 3 hundred bucks), but when this one is no longer functional I have my eye on the N3500 model Fujitsu. It has a 15.4 inch screen, Intel Centrino (low power) processor and built in wireless.
