That is some absolutely amazing modding, extremely elegantly done.
This is the new iType that I predicted Apple will launch next year, but you're ahead of them by a long shot!
It's plain awesome that you did this, and fantastic that you offer the same to others. I do have a Digitouch that would be made so much better through your mod. I would have to decide whether I'd want the Dvorak layout or Qwerty though. I'm not ordering yet, but what would your price be including shipping to Europe/Austria?
