Google has partnered with Back Market, an online marketplace for refurbished electronics, to announce a $3 (approx. 450 yen) USB drive that breathes new life into old PCs. This USB drive comes pre-loaded with the installer for 'ChromeOS Flex,' a lightweight, cloud-based OS. It is attracting attention as a measure to encourage the reuse of PCs that will be left without a home following the end of Windows 10 support in late 2025. This article explains the specifications of this USB drive and the benefits of installing it in detail.
