IMHO Google is going to lose in the email space soon as well, times are mature to beat it in simple ways, only protection they have in this space is that there is a big "optimization" part in email that is anti-spam and they are good at it. The only thing that, for me, would cause Google to "lose in the email space soon" would be the exact thing you say they are good at: anti-spam. I've started getting more spam on gmail recently but it's now only 5 or so emails a week out of thousands. Think about how good that is and then ask the question, "If it was 0, would that inspire people to go through all of the hassle to switch emails?" I'd guess that the answer for most folks would be, "Meh - 5 spam messages a week for a free email service is fine. I'd rather not change."
