I know many of you probably already know this but I thought I'd put this here. I took the keyboard from the older Mac all-in-one desktop (forgot what that's called) and plugged it into a USB port of my year-old, FreeBSD9.3 workstation at home and it worked straight away. I only tried a few alt-this, cmd-that things in i3 window manager, and I have to return it to work this morning so I might have missed something but I love this keyboard and it's good to know I can buy one and use it at the home office.
