Hey Karel, you're a fellow Newton user, I gather
Have you noticed in the control panel applet where you can teach the system to recognize the stokes you use for each character, that it is very similar to the one on the Newton. On a parallel note, I think Calligrapher also has something like that.
What I wouldn't give to have full screen handwriting recognition, along with some ability for the system to autocorrect (such that the user can double tap on the incorrect word to highlight it, tap and hold the highlighted text and a context menu would pop up offering copy/cut/paste plus a list of suggested autocorrect words, or enter a custom word, and the system will autocorrect it the next time around). Another nice feature to have in this HWR app would be a number button -- tapping on it would set the recognizer to guess the input stroke only from a list of numerals, hence improving input accuracy when inputting numbers. Tapping this button again would call up the symbols dictionary, and tapping it again would call up the alphabet dictionary. Hell, I would be prepared to pay at least fifty dollars for such an application.
