Chromebooks have an expiry date
Gosh, Gevil corporation makes there chromebook os expire in six years. After that no security fixes so the owner becomes a magnet for ransomware.
The real reason the expiry is a problem is that most companies expect that software should be completely free. Companies are not willing to pay now and not willing to pay later. To get a budget for an upgrade (not python) I told the CFO that auditors would not approve the financial statements because the software was out of date and could not be relied upon. Only when the CFO realized his job was "on the line" did he authorize a minimal amount of money to do minimal upgrades.
