heard it several times at the apple store and at the bose store. sound quality is as good as it gets for a box of that size.
in the end i decided for the altec lansing because its about $130, more portable, also has the dock, the sound is clearly inferior to the bose but still o.k. for me.
but i was close to buy the bose for $299. it's that good.
my 2 cents, andi
