Well, it aint broke, but it doesn't do everything we would like. Here is what I see as must haves: High speed USB connection WMA and OGG decoder in hardware with support for digital rights management. USB host or "on the go." Time Scale Modification (TSM) support on board. (This means the ability to speed up audio files.) On board speaker that will not increase the size of the unit and that will be disabled when headphones are connected. High quality recording capability in sterio. Microphone jack. Stable typing platform. (The unit should lay flat and stable while typing.) Label on the case. Here are some additional "nice to haves if it doesn't add too much to the cost of the unit". Bluetooth connectivity Software synthesizer (possibly optional). >>> pietruk@xxxxxxxxx Friday, April 15, 2005 11:04:28 AM >>> Larry If it ain't broken, don't attempt to fix it. No matter which speech synthesizer you choose, you will have less than pleased customers. Hence, you can't win by making a change; and, as the Book Courier uses DoubleTalk, when it comes time for Book Port owners to replace units, those who liked the doubleTalk, such as myself, would consider purchasing a Courier if they continued to use the DoubleTalk chip.
