Fans of the modular Framework Laptop who also prefer ChromeOS to Windows or Linux are in for a treat: Framework and Google are announcing a Chromebook Edition of the Laptop today. It has the same basic hardware design and works with most of the same parts as the regular Framework Laptop but with tweaks to make it a full-fledged Chromebook.

While you could always take a standard Framework Laptop and install ChromeOS Flex on it, the standard version of ChromeOS still has a few features that Flex doesn't, including Android app support via Google Play, automated firmware updates, and a few other security and device management features.
