Dave, I picked up a real cheap 7.5" Arnova tablet at TigerDirect for around the $80 mark. It has 8 gig and an Android OS.

With a PDF reader installed, and WiFi access I have installed all of your docs and all of the photos and ancillary data about my car. I carry it in the glove box now rather than carrying any books or paperwork!

They should have been standard equipment!
