The yearning for an Apple Tablet continues from many quarters. So, I guess this is one way to be able to jot down a note on an Apple device. Unfortunately it is chalk, not Ink. Russell Davies has painted some blackboard paint on his MacBook Pro. When he needs to jot down a note, he just whips out his chalk and there you go. He calls it the BlackBoard Pro.
If this catches on I wonder if we’ll see a market for mobile chalk erasers emerge?
