This is perfect for sound with a bedroom, a small living room, large bathroom (if you're not afraid of moisture on your hifi equipment ...).
IPhone connection can not only play music stored on the phone, it will recharge it. Very convenient. For owners of other audio players (not iPhone phone, laptop, mp3 player ... any), there also (and thankfully) an entry to the mini-jack format. We lose the "digital transmission" side of her we have with a computer or optical connector, but quite frankly I am not convinced that the difference is audible. Actually for me the main loss if the enclosure is used without iPhone is that you pay for features that you can not use (the highly visible front dock, the control device with integrated buttons , charging the phone from the speaker).
Finally, let's talk about design. Again I would say it depends on the use or not of an iPhone: with, great. The phone stands in the middle, the whole is pretty class. No, it's much less convincing: it was a strange indentation in front, visible an unused connector, and the sort of rubber carrier for the phone. NB: There are 2 colors of this enclosure, be careful when buying (white / gray and white / yellow).
In short: a very good camera especially for iPhone owners, provided they are ready to pay the price. I do not put the fifth star, precisely because I find the price a little high, and iPhone-centrism a bit annoying.
