One thing I would very much like to do is read my Logos books on my Nook. It seems the Vyrso could be a step in that direction, especially since I read the Vyrso books can be read in both Logos and the Vyrso e-Reader app. I guess the larger question is: Can Vyrso books be read on dedicated e-reader devices like the Kindle or the Nook? Or is the format proprietary and only compatible with the Vyrso reader? And, toward my personal concern, will some (or all) Logos books be reverse-engineered to work with Vyrso?
