Hi, I am Cathy and am new to the list. I just bought a book port and it is a used one, and now I find out there might be a better unit coming out, so need to ask these questions. I have been reading about the new book port that is suppose to be coming out. Does this mean the book ports that we now have, won't be updated anymore? Do you know if aph will allow us to update from the units we already have to get a discount on the new one, something like a trade in?
