  Were someone to invent a keyboard that gave the same satisfying clackety-clack of the old school typewriter, I'd surely invest in one. I used to love pounding away on my mom's old typewriter (with or without paper rolled in) just to hear that sound.
Even if you're typing a lot of nonsense, that sound makes you feel like you're working ridiculously hard and should be winded after finishing your assignment. I guess typewriter-computers wouldn't go over well in offices as all that noise would be enough to drive one a bit crazy, but for personal use, sign me up.
