You might want to provide updated information about supported platforms
I just wanted to let you know that RockBox has evolved considerably since being an alternative firmware for only the Archos player.
I am currently running it on my 5GiPodVideo 60GB, and it works great, with the nice bonus of allowing on-the-fly dual booting between it and the standard iPod firmware, so you get the best of both worlds without having to plug it into your PC to modify it to do that.
It also plays considerably more file formats than the standard iPod firmware, including SHN, FLAC, MPEG, and about a dozen others.
Oh, it also runs on the iRiver, Sansa, and several other platforms.
Check it out.
