I'm planning on buying the new 13-inch MacBook Pro, and in the process will be selling off my old unibody MacBook and polycarbonate MacBook. Naturally, I'm planning on doing a clean install. But, you know when you buy a new Mac, and you get that interactive "Welcome" video and then set up your own account? Is it possible to recreate that so that the person who buys the computer can set up their own account? Otherwise, how can I set up a new installation of Mac OS X w/o filling in any of the information?
