The Book Port 2 is already in development and should be released some time this summer. Nothing is set in stone. However, Larry did a show on ACB radio. He did say that it is expected that it will have 2.0 USB and draw it's power from the computer. It will have a rechargeable battery. When it is released, it won't be much different from the present unit. However, it will have much more room for upgrades and other things will be added as time goes along in the same manner as happened with the current unit. Make it a great one Sharon
