Here is a suggestion. I made this suggestion before and got totally trashed by the forum. But I will make this suggestion again, since BookPort has added the note taking function for braille users. I am not a braille user or creator. Like many who have lost vision as an adult becoming a good braille user is difficult. However, since Book Port can take notes, I would love to use this feature with an attachable keyboard. I don't know if one could be hooked up to the unit using the little USB connection. But in the future if that is a possibility I would benefit greatly by this ability. Jim Nuttall--Michigan
