I was wondering about this thing. It's a cool device. I hadnt really thought about it before, but I can load up my iPod and play it anywhere at work. Its convenient if I'm going to be sitting around in the same spot. Still, I dont know if I can justify the $350 for such a device yet. As it is, I can just use headphones on my iPod for the same purpose, and at home I have my computer and stereo.
