Apple doesn't have to make another notebook to get to sub-notebook size. All they have to do is keep the 13 in screen, trim the fat of the edges around the screen, dump the optical drive, and slim the battery down to be more flat, and apple can have a super thin, much lighter and nicer MacBook. Just give it a generation or two... thanks to high-speed internet CD's are already becoming obsolete except in times of software installs... it'll happen.
