If you look at the above image, you may think it is a screenshot of Google’s Chrome OS. But the truth is, it is the new Google Chrome Web Browser for Windows 8 devices. Google has released an update for Chrome browser in the dev channel which brings the above UI. When you launch Chrome in Windows 8 mode, you will be presented with the above UI. You will have Chrome OS like task bar with pinned apps, app list button, time, etc. Also you have Window management within this UI, you have close, minimize, maximize button as well. You can open two three windows and place then side by side if you want.
Essentially, Google is trying to mimic Chrome OS inside Windows 8. Should Microsoft delist Chrome from Windows Store? What do you think?
