I am a high school math teacher looking for an alternative to whiteboards and overhead projectors. What I would like to do is find some sort of wireless tablet that can interface with my computer. I want to be able to write on the tablet and have the writing show up on my laptop as I write it in realtime. This would allow me to walk around the room and monitor my students while I am "writing on the board". Can the Graphire Bluetooth tablet do this for me? Is there a better option available? Thank you.
