TenOneDesign is teasing us with something that might never be. In the video below you can see them using a PogoSketch stylus to Ink on an iPad. Yes, there’s Palm Rejection, but unfortunately the algorithms involved from the InkLet product take advantage of private frameworks and Apple usually rejects Apps that do this as they may break over time.
Like I said, it’s a tease. But a tantalizing one.
