The difficulty with most of them is either operating them or loading them 1. can files be transferred directly onto the memory card without using the software. 2. Does the book port read kes files or must they be converted to txt files? 3. Will it be possible to use consistently larger memory cards as they become available? 4. Is there anywhere, in the Denver metro area, where I can try out a book port before buying it? 5. I listened to the sample voice on the website, is there a place where I can listen to all the voices available? Christine
