Ok, I got the prototype. I have to say, I'm absolutely stunned. It is, by far, the most elegant phone I've ever used. It's tiny, I think if anything it's thinner than the iPod nano, although I haven't seen the latest version.
it uses the touchwheel for everything, and yes, they've done a sort of simulation of the old dial-based phones for dialing, it works very intuitively. And the capacity's good too, with 4G in this unit (apparently the black model will have 8G) It's everything you can ask for. It's sitting on my desk right now. I'm listening to Debussy, and five minutes ago, someone tried to call me and it alerted me with a soft beeping noise in the background. I just hit the "Answer" button and the music was paused. When we hung up, it resumed. No need to take my headset off.
Battery life is excellent. You'd expect it to be compromised by the design, but it isn't, indeed I can get 24 hours of playing time out of this thing and receive and answer calls and not have to recharge.
Best of all is the network compatability. The analog model plugs into any socket based on the RJ11, with an adapter for the various European connectors available too. Great for VoIP too. The digital model is compatible with most ISDN interfaces.
