Looks like a nice toy for the workout room, cottage, deck, or some other place where absolute fidelity does not matter, and where convenience for use with an existing Ipod would be beneficial.
As I own no Ipod, I am not in the market.
Sure, Apple does some fantastic marketing, but I doubt I will invest in a $300 Ipod, and another $350 for this thing... for an area where fidelity did not matter.
In fact, I have searched my home, and I cannot find a SINGLE place there where fidelity does not matter!
