You're right on driver support vs application support. There also aren't a lot of new applications in this space. I've been looking for a note taking/diagramming app with both stylus and touch support that will function as "a better piece of paper" in terms of being able to rotate and zoom on an infinite canvas; put down variable lines, grids, and dot grids; easily select and move or resize content; and I've been pretty disappointed by the offerings. I think the use case is a little esoteric in our community, I've been seriously thinking about trying my hand at creating an application to address my needs when I get some downtime from my contract work.
