How often do you use computer everyday?

i think more than 15 hours a day several hours , i used in my office and the rest of it, iam using in my home computer using means so much for me i can searching some teaching material by surfing internet i input some data about my teaching and maybe evaluating a value of student and for my private business, iam using for get some money from internet when iam in home..

I use my computers 5-6 hours a day. Sometimes I turn it off and then I use it again. Some days I don't use computer cause I have much important things to do and I'm tired to use it.

I use my computer a lot as well. I wouldn't say that I use it as much as you do, but I do use it quite a bit. But it does depend on the day. Some days I use my computer more than others. It will vary.

Nature of my job depends only upon computer, therefore, I used it nearly 7 to 8 hours in a day on an average for work and 1 to 2 hours for internet surfing etc.
