When I first thought about using my iPad for presenting at conferences and in the classroom, I thought the problem I was trying to solve was rather simple, and if all I wanted to do was connect my iPad to a VGA projector, then the solution is simple. Buy an iPad to VGA adaptor and connect the devices. Done. The problem with that solution is that the iPad is tethered to the projector via a really flimsy connection. The iPad connection port was not designed for something as heavy as the VGA cable (especially the SmartBoard cables). It only took a slight bump of the iPad for the connection to loosen and disconnect, causing the display to go blank. This solution required that the iPad be stationary. It definitely does not use the iPad to its fullest potential.
