The catalog and web-site show two different Pro Tools keyboards;; one for Mac and one for Windows. When I got the one that I ordered, at first I thought they had gotten my order wrong. The keyboard looked like the Mac keyboard, but......it had a Windows key! Apparently the manufacturer now builds the Windows kekyboard the same way as the Mac keyboard. This is good! I built a brand new machine for Pro Tools 10, and needed a keyboard for it. This new keyboard is not only great because it has the ProTools color-coded shortcuts on the keys, but becasue it is also just a fine keyboard, ProTools keys or not! I would have been okay with just a run-of-the-mill Windows USB keyboard with ProTools color-coded keys on it, but this keyboard is even better! Oh yes, does it make ProTools easier? you bet! But I use the computer for other things as well, and am a touch-typist who appreciates the feel of a good keyboard. Again, I am very pleased!
