Google's Chrome OS is based on their Chrome Browser and runs on Chromebooks, which are halfway between a tablet and a laptop. They are designed around the idea that most of the stuff we do anymore is done through the browser. A while ago Google announced that they were going to start adding support for the Google Play Store on Chrome OS so you can run Android apps on a Chromebook. Samsung announced the first two Chromebooks to support Android Apps, the Samsung Chromebook Plus and Samsung Chromebook Pro. The difference being the processor with the Plus running a Rockchip RK3399 ARM hexa core CPU while the Pro runs a Intel Core m3-6y30. That's right ladies and gentlemen, the Intel Android is making a comeback!
You need a Chromebook that has Android support. Use this list:
I’ve tested the Samsung Chromebook Pro with an Intel CPU. It and the Samsung Chromebook Plus (ARM CPU) were both released with Android support in mind.
I was going to make this one massive post, but instead I will link to other posts on the topic.
