At home I use a 10-keyless CMStorm keyboard with Cherry Mx Blue switches. Cooler Master was selling them at Quakecon

I rather like it but it's a bit annoying sometimes to be 10-keyless,so I recently bought a Dell AT101W that I posted a thread about.
At work, I convinced them to buy a Corsair K60 with Mx Reds. I work in close proximity to the boss so a loud keyboard isn't acceptable. It's a nice keyboard, but it was one that was a customer return to Fry's so it has issues once in a while. I'm not a fan of the function keys being exceptionally garbage rubber dome switches.
I had a Rosewill keyboard with Mx Browns, that I really really liked, but the usb port broke. Then the Cherry keyboard with ML switches, its a compact unit so I use it in places that call for that, but overall the feel is comparable to a high quality scissor strut keyboard (apple/lenovo/higher end dell laotops) and the layout is weird.
