If you have other interests away from it and get some exercise/see the outside and it doesn't completely rule your life then I see no problem with it. I still find time to do all the things I need to away from it and I also spend a lot of time on it. I see it no differently than people who sit and veg out in front of the tv all evening and some how that can be seen as more socially acceptable. At least the PC is interactive and you can socialise in some form if you really want. Can also be extremely productive so it's fine.
My PC hasn't been turned on for months now, generally check web on phone.
how much time do you spend on your pc ,i spend around 8 hours a day ,
is that to long.
I have been since the nude Jennifer Lawrence pics were leaked!
