Bill, I looked at my options long and hard before I bought my bookport. The manual was very thorough, and I read it several times beore I bough the device. I loved all the features that let me use all kinds of formats. I know I haven/t done everything yet that it can do, but I probably explore more features soon. I am going back to school soon, and I will be able to carry so many books on one tiny CompactFlash card. Others have already mentioned the ability to review whit you are reading by word sentence, etc. I love this ability. The bookport is a great device!
