qBits | Announcing Air Sketch 2.0, with PDF projection!

I installed this update as soon as I saw it and PDF import is an incredible addition to AirSketch. Now you can export a PDF from your favorite presentation software and display it from your iPad on the projector in your room and annotate the slides. Better yet, students can do the same.

There is a post in this, but I am using the Dropbox program and app to transfer PDFs. Any better ideas on moving PDFs to and from the iPad?
