Porsche Design Book One - any real reviews or genuine user experience?

Hi, I've followed Book One since its announcement, but I'm quite puzzled by the lack of reviews after its release. Do you know about any reviews out there? Googling gives me rather old posts, mostly "hands-on" stuff or preview-like posts/videos. I'd be also interested in first hand experience of Book One owners if there are any of you here.
Thanks a lot
Daniel
