This article's timeline is mostly accurate, but contains a few inaccuracies:

- Unified toolbar and titlebar dates from much earlier... it was 10.4, not 10.7.

- The brushed metal look was supposed to be applied to "appliance-like" apps as opposed to "document-like" apps... But Apple was never able to stick to that rule themselves.

There are a few design ideas that always turn out to be bad when implemented, but which designers seem to have to learn the hard way. Transparency is the biggest one, but I guess so is excessive rounding now.
