The concept screenshots have been designed using data that displays well in an IM-style conversation log, but how would it work for traditionally formatted email (e.g. Dear, regards, long signature, messy disclaimer, quoted text, html newsletters)? That is where the sender has one idea of how email should look like, and the receiver has another?
I would guess that just like in Gmail, quoted texts get collapsed, signatures get faded. Basically, Gmail works, too, so this is probably a solved problem.
And personally, I think the world would be a better place without disclaimers anyway, so they might as well delete them outright. But maybe that is just me.
