The Toshiba Digital Tablet PC Pen is designed to work with your Toshiba Portege M200 or M205 series portable computer. It 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. This electronic tablet pen looks and feels like a real pen and the side switch activates the 2nd mouse button. Its pocket clip design prevents loss of the pen. You can keep spares handy at home, in the office and in your carrying case. It includes five additional pen tips and a metal ring for easy removal of tip (pen tip puller).
