Matias OS X Keyboard. A keyboard with Mac OS X key positions, Mac icons for all the meta keys (including command, option, shift, control, and other symbols used in Mac OS X menus), and labels for the symbols accessible with option and shift-option. Also includes an extra control key, a tab key in the number pad, and more. As with all unfamiliar keyboards, I'm suspicious of the key feel, but the ideas are good ones.
