Because none of the current crop of PDAs, including PACMate, can handle the number of document and audio book formats that the BookPort can handle at any place close to the reasonable price of a BookPort. Remember, BrailleNote has no way to read a Daisy book, nor can you read RTF or Audible.com books on the BrailleNote, and there isn't anything about the MP3 player in a BrailleNote that can account for and use the indexing in a MP3 file PACMate only allows the user to use Daisy books if you purchase an add-on Daisy reader software, Windows Media Player can't use the indexing in an indexed MP3 file, and it is several pounds heavier than the BookPort. No matter what PDA you look at, including Maestro, EAsyLink, MPower, PACMate or an IPAQ using MobileSpeak Pocket can effectively use as many file types as BookPort. So, just because I have a PDA, I still have plenty of Good reason for wanting a BookPort Of course I don't have Dectalk speech on a BookPort, but if I could take an IPAQ with MobileSpeak pocket with Dectalk speech, add the ability to read all the file types that a BookPort can use, and have all the features such as email, etc. of a IPAQ I would think I really had something great. Now, if I could do that for around $795 I would think I had come up with a wonderful device. Oh, of course it would have to have the option of either input from a keyboard on the unit or a Bluetooth Braille or Qwerty keyboard. And, I forgot that I want to be able to add GPS for $200, including the GPS Bluetooth receiver, and both Bluetooth and wireless network need to be built-in to the unit, not an expensive add-on card, like on the PACMate and BrailleNote. Now, if you really want to please me you could add a cell phone to all of this.
