The issue appears to be that data projectors need a certain resolution for them to project from any device. Ipad apps apparently can work on different varying resolutions. That's my simplified way of explaining something that really has more complexity to it!
What I found out with the help of Gary and Lisa is that only certain apps can be 'projected'. Keynote can - but only in 'slide-play' mode (look for the play button, top right hand corner).
To project web stuff you can't just use Safari. You have to download the 'idemoweb' app and use that as your browser. Of course, you'll need to buy a vga connector - $30 or so from JBhifi.
We have several interactive whiteboards throughout the school so being able to use the ipad apps with the interactive facilities of the boards would open a whole new set of possibilities. If anyone has success doing that, please share.
