why what would the advantage of linux be?
Well, the beauty of it is that you can install software called Rockbox that will handle all your MP3's.
With this system installed your Ipod will show up as just another drive on your computer so moving songs in and out is incredibly easy. Also, since you're not using iTunes you're not tied down to iTunes' limitations.
Also, Rockbox has some cool control features that iTunes doesn't have. Go to the Rockbox website and check it out for yourself, it's pretty cool.
