I just got a 40 Gb Nomad Jukebox 3 last month, and it's probably one of the coolest portable devices that I've owned in a while. A little bigger than the ipod/nomad zen, but the dual batteries, dual line out, and onboard recording make the slightly larger size well worth it for me. Anyhow, one of the things that I've been using it for is to listen to audiobooks in the car. I've been playing around with an Mp3 joining program to splice the many files in a book into a single large file, since with the Nomad's bookmarking ability it's a little easier to manage a large file than remember where you were in a playlist. Anyhow, I noticed that if I tried to create a file that's longer than about 20 hours, the track length shows up as 00:00:00-is there a limit to the track length on the Nomad?
