I have had my Book Port for over a year and am amazed at the innovations that have been added to the unit since it's release. My experience with this list is that no one is against adding useful features. However, we purchased an accessible and portable book reader. I watched the web site where the progress of this unit was shown for over a year before it's release. When it arrived it more than met my expectations. Also, the $400 price tag is much more than many blind people can afford. Therefore, I would hate to see hardware additions that could only increase the price. Adaptive equipment is always more expensive than comparable products for the sighted. The Book Port is in line with what you would pay for an off-the-shelf product that plays MP3 and a reader for e books. To my knowledge, there is nothing on the market that will accommodate so many file types. I apologize for the fact that this has become a nickel's worth instead of the two cents that I had intended. Make it a great one Sharon F.
