Tech directors have been struggling with managing large numbers of iOS devices in their schools since the iPad bandwagon got rolling. With the iPad3 announcement, Apple also rolled out the new Apple Configurator to replace the previously existing iPhone Configurator that they recommended for also managing iPads. This app comes free for any Mac running OSX Lion and can be downloaded from the App Store.
Mirror your iPad to a macbook that is on the same wireless network.
This is awesome! The free version allows for 10 minutes, the pay version is unlimited mirroring.
