The good news in my portable audio world continues. The Rockbox project has released a working version for the iPod Nano. I got the news from the Lossless Audio Blog; thanks, Brennan! Rockbox supports, among other features, Ogg Vorbis and gapless playback. Both are said to be working on the Nano. Thanks to the Rockbox developers; I may be trying this at some point. However, for my current primary purpose, the Nano/iTunes combo is great for podcatching/listening.
