I can not afford a tablet PC. I've heard of a product like a laptop that connects to the computer.?
I attach the device to my team to allow write and develop and projecting to a screen. in short, a cheap version of a Tablet PC. I need it for teaching mathematics
Graphic tablets are probably what you're talking about. They are an electronic platform that connects to a computer via a USB port and a special pen you can write and move the cursor on the screen when you move through the book. Wacom tablet has the best, I have a Wacom Intuos tablet and it's wonderful. The size small Intous costs about $ 200, the Graphire (they are cheaper model, which may be all you need for what you want to) costs less good. http://wacom.com
