I recently lost my Book Courier and my small, four-tract, tape recorder. I am thinking about purchasing a new device. Which one should I get, Book Courier or Book Port? What are the differences among the devices? Would I be able to read RFB&D electronic, digital books with Book Port? Do you know if there is a device made that incorporates the features of a tape recorder and an electronic, reading device or am I asking for the impossible? Any thoughts? Barbara
