I've got both units and find overall that the Bose is clearly more accurate with the music. If you listen to them side by side you'll hear far more detail in the Bose but far more Bass if you listen to the iPod Speaker. I would say however that if you ever listen outside (as I did yesterday) then the iPod Speaker is better as it can go that bit louder and bassier. There are 2 other very good additions to the iPod Speaker that would lead me to chose it over the Bose...1 is the Optical Input which is great if you have an Airport Express or want to use it as an improved TV speaker from a Satalite receiver for example and 2 is the ability to use batteries.
