I love the Serenata. Pop up the speaker in the office and listen to music WITHOUT headphones, brilliant! But it is "only" a (ultra)portable stereosystem, that can be used to make phone calls with. Nothing more, nothing less. Forget the iPhone jack-of-all-trades, the Serenata is not a multi-media phone that also can play music - this is what people expect, and in my experience most dealers are not very good at selling the Serenata as a high quality ultra-portable-stereo.
The Serenata was introduced by the Danes a second phone to people already using a smartphone in their daily routine, and with a twin-sim-card it does a great job. But, again, most dealers are not very gooding at stressing the excellence of the Serenata. I love mine, and it is by far the B&O-product that I use the most these days.
So at prices like these people should hurry! The Serenata is a hidden gem - but beware: I didn't like when I first saw it, texting is very bad, there's no camera, no youtube access... but live with it and it shines through. Get your music in your hand, with B&O elegance and sound quality to match. And, yes, you can make and receive calls (but that's about it), too.
