"This needs the ability to save to a flash drive and it would be golden"
As I understand it, this isn't possible; The board isn't 'displaying' anything, the stylus just presses on the crystal and changes the state of the crystal. The only time electricity is involved in the panel, is when you press the 'erase' button, which uses a single refresh of all the cells.
Since the 'state' is only in the LCD itself, adding on a method of saving the drawing/doodle, would require a lot more electronics, and cost, than there is. Probably magnitudes more.
