It's a very convenient option if you use Chrome for Android or iOS. When connecting to a Google account, Chrome is able to synchronize browsing data and tabs between multiple PCs and devices. In fact, that's the essence of Chrome OS. In short, Chrome is basically designed to be an operating system within an operating system, the window through which you run all your applications.
With Google Chrome, as well as loading web pages, you can run complex web applications, like Angry Birds and Chrome Remote Desktop, completely free.
