Based on several reported studies dual monitor setups have shown to increase work productivity. Thus 
adding a second display even a small one can make most users work more efficiently. Today we will be looking at Air Display which is an iPad app that leverages the iPad screen as a secondary display when networked to a Mac machine. Although the iPad screen is smaller in relation to most Apple displays it still provides additional real estate for running programs outside of the main screen.
Another exciting feature using Air Display is the ability to use the iPad as a tablet input device. Using the iPad as the secondary display you can move tool palettes from programs such as Word, Excel, Photoshop off the main screen.
Air Display works on a server (Mac machine) and client (iPad) model similar to the Synergy program which allows a single mouse and keyboard to control machines running different operating systems such as Windows, Linux and OSx via networking protocols.
Air Display retails for $9.99 and works with Macs running OS X. 10.5.8 or higher. Currently Air Display only works with OS X but Avatron Software is working on a Windows version as well.
