As a graphic designer I end up sittin in front of one of these from 9 to 5 (though it's a Mac). After work, I usually come home and fly AH or I go down to the recording studio I share with my band. There, we built a Pro Tools system... and since I'm the only one who knows how to work a computer I end up in front of it doing alla the recording/editing.
The only TV I watch is basically the West Wing, Sopranos, hockey and football... so if I'm at home, I'm mostly on this thing.
It's pretty sad.

But... lets see... AH, Google research (just looking up stuff), Kazaa downloading movies or old TV episodes (Band of Brothers, Sopranos), Salon, Email, homework.
