I saw this at wired and could not resist posting about this as another optional keyboard for your iPad. It is will only set you back $799 to have a 1945 Royal Aristocrat typewriter as your go to keyboard for your iPad. Take a look on Etsy.com if you want to know more.
If that seems a bit pricey, you can get the conversion kit for only $75 and supply your own typewriter.
Brings back memories of the data entry devices from Terry Gilliam's 1985 movie Brazil where there was a typewriter attached to such a small screen that they had a huge magnifying glass in front of it to be able to read it.
