We first saw Griffin
wireless iPod speakers way back in January at CES
, and it looks like they're finally shipping. The detachable speakers each contain a battery with enough juice to last 10 hours, and the Evolve base can charge both the speaker cubes and a docked iPod. Apparently Best Buy is getting the exclusive here -- the system costs $299 at ol' Blue, but those of you morally opposed to bricks and mortar can cough up an extra $50 and buy direct from Griffin for $350.
