Montana 700 text editor?

These units are big enough, and have a Multi touch screen/keyboard, that a smartphone style text editor is a possibility... I'm not asking for it to run Word - but how about some sort of a notepad? There really hasn't been a previous Garmin on which it makes sense, but these could... 

If Garmin won't do it, are Connect IQ apps flexible enough that some clever person could write one? Of course this would require that the on-screen keyboard is accessible through an api (or that some developer also writes their own keyboard)...
