The perfect companion to your Intuos4 tablet, Wacom's Intuos4 Mouse functions as an alternative to the pen. Use it for everyday computer use or for those tasks when a traditional mouse pointer is preferable. The mouse has two additional buttons, and each button and the scroll wheel are programmable. The mouse is wireless and doesn't require any batteries, so you can just place it on your tablet and be able to use it immediately. It also has a unique Tool ID, so the settings you create for the mouse will be remembered without affecting the settings of your other input devices.
