Here are a few pictures of my Macbook mod to the Dvorak keyboard layout. Though it is not necessary to change the keycaps over, it does look pimp! Be careful when popping off the keys, as I have messed up a key before on my Powerbook. It isn’t cheap to fix!
In OSX, all you need to do to type in the Dvorak format is go to International and tick the Dvorak button. I recommend the Dvorak/Qwerty option. It allows all the keyboard shortcuts to revert back to Qwerty when the Apple/Command key is pressed. Great for Command-C(Copy), Command-V(Paste), etc…
I switched over about a year ago, and have been loving the typing experience. I am finally typing at about the same speed I left in QWERTY, but find my hands aren't moving around the board as much.
Check out the pics!
