Android apps for Chrome OS are the most substantial additions Google has made to the platform. since its debut. While it has been argued that it has had a debilitating effect on some of the initial promise of Chrome OS i.e fast, simple, light and cloud-based, the addition of Android apps is Google's admittance that there are some use cases that are better covered by local apps than with web-apps.
Google is expected to continue to improve Android app support on Chromebooks in the coming months and has already added support for split screen in developer builds of the OS.
