Who hasn’t doodled a Michaelangeloesque creation in science class? But then that masterpiece is forever bound to your science notebook and man, no one wants to keep that thing around. The iSketchnote ($119) is an iPad cover that lets you digitize your notes and sketches in real-time with the added value of a hard copy for your files. Thanks to some fancy sensors and technology we can’t begin to comprehend, you simply draw on a piece of paper on top of the pad and whatever your write instantly appears on-screen.
