Android president Sameer Samat confirmed that Chrome and Android will be combined into one operating system to “make your laptop + phone work better together.”

Google is building Chrome OS atop Android, but there are a few things it has to get right as part of this ambitious project.

Android has an enormous app ecosystem, but many of those apps still struggle on larger screens, like tablets. And Android doesn’t have great multitasking or window management, which are both important on large displays. ChromeOS, on the other hand, does browser stuff and window management really well, but doesn’t really support non-web apps.
