Nice review, but there are a few other media players that I would have included.
One being Cowon's Jetaudio Media Center ( http://www.cowonamerica.com/products/jetaudio/
It plays EVERY audio file you could think up(Considering you probably won't mention many of the files it can play)
Plays most video files as well
Audio Quality would kill iTunes, Winamp, WMP11 if you spend a extra 8 bucks to buy the BBE sound enhancements
That at least would have to go in the honorable mentioned if not part of the main review
