Our previous post about a MacBook Dvorak keyboard mod generated a number of comments, including hearty suggestions from several our readers to try the Dvorak keyboard layout. Now desktop users of the Apple Keyboard (both wired and wireless) have an even easier option for testing the Dvorak layout. zCover is releasing a preprinted Dvorak layout skin that fits the Apple Keyboard and doesn't require any popping off and rearranging of your keys. It has the additional advantage of glowing in the dark and, of course, protecting the keyboard.
Incidentally, for those who didn't know, OS X has built-in support for the Dvorak layout in the Input Menu of the International tab of your System Preferences.
