It is great but as a Magna Doodle (basically e-ink but manual and magnetic) kid, I can’t be convinced to switch to drawing only continuous lines on a tank-like interface. Yes, the effective resolution is about an order of magnitude higher so you can fit an entire poem instead of a short sentence but drawing letters is 20 times slower. Also, there is no monopoly, lots of companies make Magna Doodle clones (I never had the real thing either). If I could make a sufficiently dense (1mm) array of powerful inductors, I would use a scanner mechanism and an Arduino to play 30fps Bad Apple!! on it in a timelapse, showing its superiority in speed (5 seconds per frame) and filling dark regions. (No, the inductors cannot be staggered like nozzles in inkjet printer heads because that would produce streaks by disrupting previously blackened cells.)
