I have 4 PCs in my house, one running as a server , 2 media centers and the main system I use mainly for gaming and a bit of Sony Vegas video editing.
I also have a laptop that I use for work.
Totting up how much my "main" pc cost its worth just as much as the the others put together (minus the laptop). As I don't game a quater as much as I used to I find this totaly stupid and to be honest a bit of a waste, it sits there most of the time unused and only comes out to play for a couple of hours at the weekend. I would say my laptop (what I am using right now) get used for a good 10 hours a day for work and posting on this forum, the media PCs get used a few times a week, the media server is always doing somthing but the £2,000 gaming system collects dust.
So what uses do you have for you "main" PC?
