As with anything Bose, your first instincts are right: this is severely overpriced. I can see why they charge so much: so they can pay off all the full page ads and infomercials to market this thing.
Consider that $600 can actually get you some very decent and much more capable stereo equipment, in terms of features and sound quality. Also consider that, for $600, it doesn't even come with a USB or SD card slot. Still requires CDs? Seriously how long can they possibly milk this product (and their other products) for?
I think the phrase that best describes this is "it's good for it's size but don't expect miracles". And I honestly think the only reason why this thing is so great is because it's competition is alarm clocks, and no alarm clock sound good. But you will never find this device and "audiophile" together.
You have a couple of photos that are great... you must be very good at photoshop!
