Ricoh recently released a very cool new iPad app called RICOH TAMAGO presenter. It's a paperless presentation tool that allows you to hold meetings and give presentations without bothering with printed materials.
Instead of handouts, you can share the presentation on your iPad with the iPads of your meeting attendees. As you conduct your meeting, you can even make notes and markups on the displayed page of your presentation.
You can also integrate RICOH TAMAGO presenter with your RICOH network projector. We tested this feature in-house and were very pleased with how easy and seamless it was. Setup only took a few minutes and it allowed us to project our documents wirelessly from an iPad.
This is an incredibly useful tool for ad-hoc meetings when you don't have time to lug your laptop into the meeting room, plug in all the cables and get setup. With a few button clicks on the iPad, you can turn the projector on and begin the presentation before you even get into the conference room.
