It's not a tablet. It's not quite paper, either. Instead, the Blackboard Electronic Writing Tool uses Liquid Crystal Paper technology to become something in between. Its 8.5" x 11" surface lets you write as naturally as you would with pen and paper, with the ability to erase mistakes or clear the entire thing with a single button. The surface is semi-transparent, so it works with both the included templates and anything else you might want to use as a backing — including digital devices like iPads — and with a five-year battery life, you don't need to worry about adding yet another charger to your arsenal.
