...no it ain't on the iPod. That ship has sunk. It's on an iAudio X5 60 gb with the Rockbox software. There is no danger with the installation of the Rockbox onto iAudio equipment because it installs exactly the same way as the native software, and you can always just remove it if you so desire with no effect on the included files (in fact, the iAudio site links to Rockbox). I had to work a few bugs out of the system, but I can use a standard file tree navigation, you can also use it to search by id3 tag, but I prefer this method, as it is almost identical to the one I used to use on the iRiver. And it is completely gapless.
