Serious How much time on your PC per day

I'm a developer, i use my PC to work and to have fun so... i'd say more than 8 hours every day

6-7 hours a day depending on what I am doing, usually it's 6-7 but sometimes more, Sometimes less

Well I go to collage for 5 hours, sometimes I attend Army Cadets; So around 5+ hours developing my DarkRP server.

6 hours working in front of pc plus 2-4 hours playing or just relaxing at home. sometimes more

The longest pleasure at the computer was on a 3-day lan party with around 65 hours of continuous play Unreal Tournament. I'm not playing another minute today. I work most of the time.
I sit daily from Mon-Fri from 7:30 am to 12 pm in front of the computer (16,5 hours) for exactly 20 years. Weekends vary a lot. Sometimes only a few hours, because I am on the road and do sports.

Better than 10 ! I use all times for my Offers and UG ! Always on my computer because this is machine help me make money
