Isn't this a best practice for UI overhauls? Whenever Google changes Gmail that's exactly how they handle it.

I think most gmail overhauls have been significantly less major than Windows->Metro. The complaints against Metro don't seem to be so much that people haven't warmed to it yet so much as that it doesn't gel with the way they want to work on a desktop/laptop computer at all.
