If you’ve wanted to use a mobile tablet as a Wacom Cintiq-like graphics input device for your computer, for a long time Astropad was the app that many turned to (a company called Avatron also offers Air Display for iOS and Air Stylus for Android). Now Duet, Inc. has introduced Duet Pro. These solutions display desktop applications such as Adobe Photoshop and Adobe Illustrator on an iPad, letting you use a stylus on the iPad display to draw or paint directly on the desktop document.
Both Astropad and Duet Pro are much less expensive than a Wacom Cintiq…if you already own an iPad. If you’re deciding which one to use, you’ll need to know the important differences between them.
