You can see the new version in action in the video above; I’m weirdly reminded of the Windows 95 Start menu. As with many Google updates, this will get rolled out gradually; right now I’m still seeing the old interface on my system.
Like most changes, it will make some of us nervous, and it’s clearly designed to encourage people to use Google+; all its key options remain visible, but getting to other services requires more work. That’s not great if you’re indifferent to Google+ (though it definitely has its uses), but I suspect Google won’t be making it easy to switch back once it goes live.
