Yeah, this is a great tactic for those inclined. I'm afraid I'm too impatient. I can type much faster than I can write long-hand, and there's a better chance of my being able to decipher it later. :)
While nobody makes actual physical typewritters anymore (to my knowledge), they can be had used for very little, so you could have the best of both worlds by writing your drafts on a typewritter.
