I'm surprised by the reaction in here- yes, it's an addition to the standard e-mail system. Do we really want that system to stand absolutely still? If that's the case, why are we cheering so much web browser development? Surely a browser from 1997 should be good enough for anyone?
That'll be a first. Historically, Google has deeply neglected Apps users. My Apps account didn't get G+ until almost a year after it became generally available.
That's a funny way of looking at it. I pay Google money for my account so that I have, above all, a reliable system to use for my business.
No beta bullshit. And with Google Apps, that's what I get.
Regular users are the guinea pigs and once a feature has proven itself year(s) later, it's added to Apps. As someone who runs a business, I'm quite happy with that approach.
I get all the latest and greatest on my personal GMail account, I don't need it on my business account.
I think everyone would be happier if Apps users could signal to Google they would like to be a 'new features beta tester'.
Also I can see uses for this on business systems. Notifications are send via email, could be useful to make it possible for users to also take action in their inbox without proceeding to web.
