okay fine i'll start some shit: windows metro had a tremendous amount of potential. it was just overambitious in the input method stuff. but the visual design principles? they nailed it. faithful to the international style, really strong type, i love the wayfinding signage metaphor. really really good stuff.
also, bento boxes...where have i seen those before…
