"A feature that has long been request by educators has finally arrived in iPad 2: video mirroring. Video mirroring shows exactly what's on your device's screen on a second display, like a projector, television, or monitor. We're used to video mirroring with laptops--many teachers do this everyday.
iPad 2 requires either the Apple VGA Adapter or Apple Digital AV Adapter. The VGA adapter connects to most projectors while the digital adapter connects to HDMI, which is common on newer televisions. Apple Digital AV Adapter also outputs sound while the VGA adapter outputs only video to the display."
Though it won't be released until November 2009 and there is no price attached to it, the MiLi video projector may be just the tool to add value to students iPod Touches and iPhones.
