Leave the VGA dongle at home! Project PDFs and photos directly over WiFi.
Air Projector projects PDF documents and photos wirelessly from your iPhone or iPod Touch to a browser connected on the same local network. No additional client software is required.
Just fire up Air Projector and type in the displayed URL in your web browser. Then flip through the pages or photos on your iPhone and the remote display updates automatically. Tap and hold to show a laser pointer on the remote screen.
Send PDF documents from Mail, or a third party document manager such as Dropbox, to Air Projector to present them. Works great with exported PDFs from PowerPoint or Keynote (note: transitions and animations are not stored in PDFs).
Share presentations with remote colleagues via online meeting or desktop sharing software (such as iChat).
