If you’ve been shopping around for a new graphics tablet, the folks over at Genius have unveiled the latest additions to their MousePen series, with the M508 and the M508W. Both tablets offer the same features, except that the M508W offers the additional benefit of being wireless. These tablets offer a 5×8″ work area that is customizable, with four physical buttons that can be programmed to meet your needs, along with 13 programmable keys that can be accessed with the pen via a wireless 2.4GHz signal. A Genius mouse is also included in the package, which is an added benefit if you still have a hankering for a mouse. The M508 will set you back $149, while the M508W will cost $199, both tablets will be shipping in September.
