Great post! I learned a lot and its interesting to see the drastically different directions Apple, Google, and MS are taking. Remember when everybody would just rip off everything Apple did? What would say the opposite of flat design is? 3D Design? Skeuomorphism? What would you consider Twitter Bootstrap? http://twitter.github.com/bootstrap/getting-started.html#exa...

I'd say it's Almost Flat. Colors are typically mainly solid, with mild gradients, and there are pervasive but understated borders with round edges, etc.

It looks like it's going flatter in v3 according to this tweet from @mdo the other day: https://twitter.com/mdo/status/291831248576458752
