I believe you meant aspersion? The only interesting criticism I've seen of Windows Phone's design language is that by eschewing most forms of visual affordance, it erases a lot of distinctions between actionable and non-actionable elements onscreen. I don't personally see this as a good or bad thing, though; it just requires a different set of conceptual tools to build affordance.
