But, as anyone who has seen or used the subsequent Windows operating systems knows, the paradigm that Microsoft spearheaded was explicitly designed to be flat, and lack perspective. Scher's embrace of perspective was the polar opposite of the minimalist project Microsoft was engaging in. Her logo was wholly inappropriate for the context.

This is not accurate tho. The logo works really well with metro UI, BECAUSE there is subtle connection in perspective: when you hover over the tiles, the tile does tilt animation, which would result in similar perspective as the logo. This is masterfully done in my opinion.
