Toshiba Digital Tablet Pen lets you interact with your Tablet PC in a more natural way by incorporating the convenient and intuitive aspects of pen and paper into the PC experience. Using this tablet pen and Tablet PC Input Panel, you can write directly on the screen and save your notes in your own handwriting - or convert them to typed text for use in other applications. The pen can also handle common mouse and keyboard tasks like opening applications, selecting text, and displaying menus. Since the grid provides the power to the pen through resonant coupling, no batteries are required. Keep a spare pen handy.
