Where colorburst loses

Where it wins

Compared with ChromeOS Flex

Flex is Google's own way of putting ChromeOS on an old PC, and it is good at it. The difference is the account: Flex requires a Google sign-in and is tied to Google's services. colorburst creates the account on the machine and talks to no one. If you want Google's ecosystem, use Flex — it is better supported.
