iOS 5 is about to drop on the world, and I saw a feature that could be a big deal for those of us giving presentations on iPads - or even iPhones.
This means that for $99, you can connect the output of the iPad to any TV or display. This would also work for an iPhone. This combo nicely bridges the gap between “hold the presentation in your hands” and “show on a big screen/projector”.
It also means the presentation kit for some scenarios can be very, very light. An iPhone and the hockey-puck-sized AppleTV can fit in your pocket.
