Lol, trust me, I wish I could NOT use this...
I have two computers that I game on. My MAIN PC is at my work and it has my razer habu (wired) mouse with a desk and a 19 in monitor. That computer is a beast and its been running great since I built it in 2011. i7 3550k 16 gigs ram 2 gig g-force, the whole works.
A few weeks ago, I got really tired of being at my workplace staying late and playing games. So I tried to figure out how to play CSS on my media computer at home. It's connected to a 42 inch vizio led tv, and the only other furniture in this room is a bed. I can't really fit too much, so that's what I'm working with. Most of the time I use like a TV dinner tray to hold this bluetooth logitech keyboard and the stupid apple magic mouse on a surface area made for ants. That said, half the time I just use my mouse on my leg or on the mattress which results in TERRIBLE control. Basically, playing conditions at home are really crappy, I might as well use an xbox 360 controller.
