Yeah, dunno. I've seen the reviews and so on, but having played with metro on some devices, admittedly just in a store for maybe 10 minutes a few times, I just don't like it. The large text that just kind of runs off the side of the screen, and content hanging off just at the right edge to scroll to feels sloppy somehow. Also, I find the up transition jarring (kind of a page flip thing). The live tiles are sort of neat, but overall I don't care for the design aesthetic.

This is totally subjective, and probably just inertia w.r.t. what I'm already used to, but I just don't care for it, no matter how well reviewed it is.
