On a related note, does anyone have an old Newton that they want to sell? I have an original Newton that I have just got going after about 8 years and its so cool I'm thinking a 2000 model (is that what they were called?) would be even more fun. It even does the 'puff-of-smoke' thing just like deleting something on OSX. Talk about ahead of its time.
