Remote Conductor: Track - Launch - Switch Review
Remote Conductor 1.0 turns your iPad into a sophisticated remote control for your Mac laptop or desktop over WiFi. Note that you will need to install Conductor Server software on your Mac to enable this magic.
It takes a few minutes to get used to Remote Conductor. The app is intuitive but also complex, so I was thankful the very thorough in-app help.
Overall this is a technically impressive app - and could be useful for presentations and in classroom settings.
Remote Conductor provides a wireless trackpad; I am hoping that it will add a wireless keyboard in the next revision.
