Samsung Galaxy Note keyboard software Is the software for the Galaxy Note keyboard (and its possibly its other unique features) available for other Android devices?

I am willing to pay and I also have a rooted phone, if that helps me get these features.

Specifically, as shown in this video, at about 22 seconds in, there is an option to write with a stylus which gets automatically recognised as words, etc.
The "Graffiti" writing technology from the old PalmOS devices is available for Android now, and supports letter at a time text input with a stylus (or presumably a finger). Graffiti for Android.

However, something like DioPen or PenReader seems to be more what you're after. They both have very mixed reviews, and do seem to be better on some devices than others, and take some getting used to.
