Avatron Software is already known for its Air Display 2 app that turns your iPad into a second display for your Mac, and now they're turning your iPad into a graphics tablet, too. Their new Air Stylus app works with more than 30 Mac art and design apps such as Photoshop and Illustrator, and supports pressure sensitive styluses, plus it lets users draw on their iPad screen much like Wacom's pro-level Cintiq tablets. It links your iPad and Mac via Bluetooth, so there aren't any wires to get in the way. Air Stylus looks like a cool alternative to using an actual graphics tablet, and is an awesome example of just how versatile the iPad really is. Air Stylus is priced at US$19.99 and is available at Apple's iTunes-based App Store.
