Switching to Haskell Cafe; I hope you read that list, John, since it 
seems more suitable to this kind of question.

Maximum coolness!  When you were targeting the nokia, how did you handle 
the radically different user interface?  Did you have to establish a 
mapping from one of the Haskell UI packages to the Nokia equivalents?  
If so, which one did you pick, and how much time did it take?

I'd love it if I could get this working for the Palm....
