This is great! I actually talked to a customer service rep in February, and they said they had no plans to support any of the readers. I did point out that the zip folio in the compact size was nearly perfect, and that all it needed was a clip for the Reader's hinge-binder thingie. I guess Velcro is an acceptable stopgap.
However, it looks like all they did was nix the "Circa" rings, so it can't carry both paper AND the Reader.
