Works Well

This app does what it says - it show a PowerPoint (PPT) file on a TV / monitor or projector. It also supports the Apple Digital AV (HDMI) Adapter. Just email a PowerPoint file to yourself, open the message in Mail, tap on the attachment and tap "Open In.." and choose "Presentation". Embedded songs and movies are not supported, just text and graphics.
