I had an identical reaction -- if I didn't know better I would have thought the lead in "The theme looks just gorgeous, doesn’t it?" was sarcastic.
I honestly don't get Metro, or the love of it, though I know that taste for such things are entirely subjective. A ridiculous low data density, elements not conforming to usability / aesthetics relative to their container (the whole giant text covering multiple viewports thing), a mishmash of contrasting colour tiles. It really, really isn't my thing. I hear it sells to people like the Woz, but in my opinion it's just a terrible interface that is heralded purely because few have used it in any functional way.
I have, and I genuinely think the interface is great, but that third party developers often get it wrong (resulting in the low data density you mention). There shouldn't be any mish-mash of contrasting colour- WP has one highlight color, along with the black and white. The giant text covering viewports is an indication that you can swipe left or right to see additional views- there isn't a parallel in iOS so if you haven't experienced it then it does look strange.
I went to a presentation on Metro design and I think it looks very nice indeed. The clean looks of the interface and the high emphasis on typography and positioning appeals to me more than the skeuomorphic designs of certain iOS apps. The presenter (a guy called Shane Morris) covered quite a few aspects of the ideas behind Metro and I have to say MS is being quite bold about the whole thing (whether they deliberately decided to reinvent the desktop or not).
Functionally, virtually no major apps have been converted to a Metro design, and we'll probably be working in traditional mode for most serious productivity tasks for some time. It remains to be seen if the Metro approach will fit more complicated programs with many, many functions. Nonetheless, I give MS props for taking a big leap with desktop design, whether it pans out for them or not.
