The $99 Apple TV has a neat feature in that you can use it with an iPad to project presentations from your iPad to a screen or wall in any meeting room.
You can create presentations within a number of applications available for the iPad and then project what appears on the iPad via an Apple TV. Popular iPad applications which can be used to create presentations include Apple’s Pages (sort of a combination between Microsoft Word and Publisher), Numbers (which is similar in scope to Microsoft Excel) and Keynote (which is comparable to Microsoft PowerPoint).
Here’s a link to a PC World article, titled Apple TV Finds a Home in the Meeting Room, on the subject:
