I agree, and it's tough because someone needs to be the middleman in all this when it comes to messaging, because with messaging there is a guarantee of delivery even if the other party isn't online. It doesn't mean that Apple, MS, Google, RIM can't all be a middleman for their respective users, but they certainly didn't mention that in the keynote.
