Interesting. Looks like there is some Inking in the iPhone’s future. Sketches (Alpha version 0.1) allows you to jot down notes, sketch a simple diagram, or annotate a picture, on your iPhone. What’s intriguing is that it uses the old Etch-A-Sketch method to erase. Apparently you just shake your phone. Maybe we’ll get Rob to test this out on his iPhone at the GBM Meetup tomorrow.
