The pen is sensitive to 1024 levels of pressure, allowing intuitive adjustment from thin to thick lines. The tablet can switch from a widescreen 9 x 5.5 inch workspace to a standard 7.25 x 5.5 inch workspace to match the screen of the user. A rolling pad allows for quick operation of a number of functions, including scrolling in four directions, zooming in and out, volume control, and fine tuning the brush-width. 26 shortcut keys allow for quick access to functions in Office, Internet, and Windows Vista. Two buttons on the pen can function as left and right mouse buttons. The PhotoImpact software for Windows is also included to allow for quick editing of photos.
