Apparently Mazda has partnered with Phatnoise to start offering Phatboxes as an OEM Mazda accessory. If you haven't seen a Phat box click here. Does anyone have any first hand experience with these things? Is the sound quality digital, which would be better than an ipod? Do they work well? Info would be appreciated. These things seem like a good idea. BTW, retail price is about $680.
