Hmm... let's see... I'm a teacher, so I actually have to, you know, teach a little. 😀 I'm probably on my iMac here at school a couple hours a day (all of my planning and lunch times, plus checking my email and some news sites every time I get a few minutes break). Once I go home I spend the rest of my evening staring at these "glowing rectangles" - either my 17" iMac (too small), my Acer/Win 7 laptop (not a Mac 🙁), or my 50" plasma (just got it, and easily my favorite). Does that count? 😀 All in all, I'd say have around 5-6 hours of computer time, probably 8-10 if you count in the TV, too.
