Looking at the new layout of the Google search results for smartphones and now tablets, it's hard not to see a visual connection to the way Google+ looks. It's part of Google's new strategy to optimize the search experience and really fully integrate all of their services into one recognizable package. All your search results can be reduced to a specific type i.e. news, blogs, images, videos etc. Google appears to be implementing this new look with tabs for quick and easy access.
As part of the new Google search experience, you can now enjoy continuous scrolling as well as view images in both landscape and portait mode. And in order to emphasize its role as a global player, the new tablet search interface will be launched in 36 languages. Now that's some serious work!
Keeping the development of Google+ in mind, it looks like the Google experience is becoming evermore encompassing and broad. And until anyone can come along with a search interface as simple and beautiful as this one, all of the other search engines might as well just wave a white flag of defeat.
