There's new Google design pixels all over the place. Have you checked out Gmail on an iPhone? Google's managed to make all of its 10 bajillion services come together in what feels like one superwebapp.
Just pull down on the blue bar in Gmail or Google Talk or Google+, and suddenly you see they're just a tab in a row of buttons. Click the more button and your mail (or whatever) just slides down, revealing quick, clicky access to a bunch of Google's other products. And you can tab between search stuff, apps and your six thousand Google+ notifications that I changed my profile picture.
All in all, it's pretty swizzy.
