Google today announced Chrome OS Flex, an early preview of a new initiative that aims to bring Chrome OS to virtually any PC (and older Intel-based Macs). Built on top of CloudReady, which Google acquired in 2020, Chrome OS Flex is aimed at enterprises and educational users who want to prolong the lifetime of their existing devices, but anyone with access to a USB drive can use it to give an older PC — or maybe even a low-powered new one — a new lease on life. There is an obvious sustainability angle here.
