Was going to watch the first five minutes, and ended up watching the whole thing. Interesting perspective, and love the way various products are becoming "elastic".
Definitely still not sure about the new gmail layout though, you just see far fewer messages on the page, and I think that slows me down...
I tried it, but still wished it was denser, so switched back almost immediately! Clearly, others have sent similar feedback. Perhaps a "Preview (Dens<b>er</b>)" will come out!
