Google has been trying to make its home, Search page feel a bit like your desktop, giving you a presumably quicker way (in one place) to access all of their products (and your stuff), with top priority being given to rolling out Google+ integration across each and all of those products.
And today they have introduced their new redesign, according to Google:
We’re now ready for the next stage of our redesign—a new Google bar that will enable you to navigate quickly between our services, as well as share the right stuff with the right people easily on Google+.
Instead of the horizontal black bar at the top of the page, you’ll now find links to your services in a new drop-down Google menu nested under the Google logo. We’ll show you a list of links and you can access additional services by hovering over the “More” link at the bottom of the list. Click on what you want, and you’re off.
