While both technically wrong and true of every computer, many Chromebooks can run non-Googled Linux distros and far outlive their support term… $50 might get you a very nice, lightweight, and portable “netbook” on the used market that you can use another 5 years for basic tasks.

ChromeOS, outside of being Googled, is quite capable (crostini is really nice), well secured (minus Google privacy concerns), and generally a nice user experience. You can even run Firefox and avoid browsing with Chrome.
