Why it is in the section "graphic tablets" and did not understand. If you remember, children used to have tablets of the same principle: I drew patterns on a black background, ran a plastic special stick on top - everything was erased and can I draw again? Here is a tablet. You just draw\write in one turquoise color, moving with the stylus, then you press the button - everything is erased. For me, as for "tasks for the day", so as not to keep everything in my head - it fits perfectly, but be careful when reading the characteristics. There is no memory-saving-transfer to the phone / PC, etc. - there is not a trace here, this is a tablet of a different type.
