tboehme describes how he uses two external 19″ monitors with his Tablet PC Thinkpad X61t. He uses the Matrox DualHead2Go to make the connections. That gives him three working monitors with almost independent images at the same time. It appears at the time of his post that this set up has some, limited, potential as a whiteboard for teachers. Thanks for the glimpse, tboehme, to an off the shelf teaching tool available to teachers now and in more refined form in the nearer than later future.
