you are missing the tablet input panel, which is more than just handwriting recognition and is very convenient for filling out short forms and things, though i don't know if it does finnish and i do know that it doesn't work as well as it might with firefox and probably opera.
also, you are missing a few handy utilities (some people would say that missing one note and journal is the biggest thing but i am not one of those people). don't know gobinder, but that may be a substitute.
in my mind the biggest loss is hardware - touch screens are not pressure sensitive and you can't rest your hand on the screen while you write/draw like you can with a digitizer.
that's what you don't have, what you do have is something that is as light or lighter than any of the tablets yet still has a keyboard. and it has a resolution that is actually slightly higher than any tablet except the M200. if the flybook had had a digitizer and an efficeon instead of a crusoe i would have gotten that for sure.
