This sort of feature always makes me sad that they announce features before rolling them out to everyone. Now I can't wait for it to show up in my account.
Yeah, I really with this was a google labs feature so I could try it out right now. Although the fact that it is not a lab feature means they are taking it quite seriously.
I can't agree more. I was really disappointed when found out that I need to wait for release. Most likely I'll forgot unless it will appear on top of HN next week.
They announce this sort of thing as "New Features" in the GMail interface itself. So you don't need HN to remind you.
It should be along shortly, if not already. I've got it in my personal gmail account and my apps account.
