Well, I don't like the Hemingwrite, but I like the idea. So many good ideas here. First, Moose is totally on to something, in that you can type on this thing without any fear of your stuff being read by google, the N. Koreans, the NSA, the CIA, the illuminatii, or your mom. I may sound like I'm joking or crazy, but I'm not, when the revolution happens, you don't want the gov'mint knowing your secret plans.
And if Sam wants to make a competing product, I suggest calling it the "Fitzgerald-write", which is a better name. Also, it lends itself more to a jazz-age theme, and the case could be a cool bakelite art-deco style from the 1930's. And you could have different versions, like the "Gatsby" which could have gold-plated accents, or the "Daisy" which could be pink, or the "Zelda" which could be totally insane.
