MyPaint got me excited, but the three screen implementation was so clunky that I couldn't dive in like I wanted. I guess the issue is that I don't "have to" sketch on the tablet, so a half baked UI interaction can dissuade me and leave me to other solutions.

Xournal is pretty nice for notes, but doesn't quite cross the line beyond that.

Those sketches above are nice. My sketches (of UI designs and flows) end up being not nearly as elegant. I've just held back and use paper and pencil/pen.

But I am really waiting with bated breath for a sketching/drawing solution that makes the tablet shine. So Awe215, I applaud your effort, and the efforts of the folks who have given us MyPaint, Xournal and the others. I'm still waiting, and I am still optimistic!
