indeed, it strikes me as odd. Maybe it's just that the visual style of Metro isn't suited to being presented as a screenshot, but to me it looks like a simple mockup, there's no "gorgeous" about it. Functional though.
It occurs to me that the Metro theme really is that ugly. When I saw the new Windows logo, I thought something similar to your reaction. This isn't looking good for Microsoft :(
Try using a WP device. Seriously. The Metro theme is anything but ugly. Minimalist, perhaps- and maybe that isn't your style- but it isn't ugly. I would choose it over Apple's "making your address book look like a leather-bound book" approach any day.
