On keeping input bandwidth high with a paper-like interface:

>> [I type] faster than I write and my writing is not very good.  My typing is
>> so much better than my writing ...
>An obvious answer is to draw a typewriter keyboard on your LCD display

But then some people will claim they need tactile feedback to type
effectively.  I think that you'll need a 'real' keyboard for a while.

I believe that people will adapt to whatever input modality they're 
using the most, so that the handwriting speed will improve with practive,
eventually surpassing typing.  [Don't count on anyone except the computer
to be able to recognize the chicken-scratch anymore.  I'll bet that even
the user won't be able to read it back the next day.]
