Hey, these are the guys from M-edge. We developed a neoprene case for the Sony Reader, although final fit and finish has not been completed. Like nearly everyone else, we haven't been able to get our hands on a Reader. We expect to have the final case available shortly after release of the Sony Reader.
We are nearing completion of a case for the iRex and eFlyBook. The iRex case is a little different from the Sony Reader case. It actually looks like a book and has a fold over lid. The eFlyBook case will include a leg band, and we're working a concept to allow for yoke mounting.
We have some other accessories under development...although we're not ready to get into the details of those just yet.
We invite your feedback and comments. Thanks!
