This is a pretty interesting idea. Inklet is an app designed to work with a pressure sensitive trackpad, like that on the new MacBook or the Apple Magic Trackpad 2. It ships with a Pogo stylus, though it will work with another stylus or, in a pinch, with your finger.
Inklet is designed to work with existing graphics packages like Photoshop, Acorn, Pixelmator, and Corel Painter.
Inklet and a Pogo stylus is currently on sale for $26.18. I’m assuming the stylus is pure stylus, no electronics, so set your expectations accordingly.
