I'd say the one really important thing web is missing is notifications for when your not on the site. I don't really know how a browser could ever implement in a similar fashion.
Email, or SMS? Though I don't see why Apples Push Notification Service, can't be opened up for the web side. They are already going through Apple servers correct? Safari has push notifications, let's combine the two.
