Wonderful keyboard. Bought three of them for my Windows machine, Linux machine, and of course my Mac. Only problem with using it on Windows is that it doesn't have the Windows delete key, only the Mac Delete key which is in effect a Back Space key in windows. Anyway, there are lots of free key remapping utilities available and I remapped F12 to be a Del key, F11 an End key and F10 a Home key.
Keyboard feel is great. Keys are proper size, key touch and click is perfect, and of course the keyboard itself is light and smart. No problems with paring to any of my machine.
