sorry... it really has to be an iPod of some sort.

so many different companies make docking stations (with speakers - I've got Altec Lansing in-motion which must be about 5 years old) for them... the iTunes software is great... and believe me, it took me a loooooong time to pass over to the iPod side. ^

Just don't get carried away by having as many GB as you possibly can. I travel a lot, so am very happy with my old 8GB Nano.
