Anyone procuring #Chromebook hardware with public funding, like for schools, should be aware that the expiration date on that hardware is artificially created by #Google since they maintain their firmware as incompatible with other standards. Given a properly structured firmware, any old #Chrome device would run #Debian or other #GNULinux just fine. The #Chromium team operates in public and has done a good job of releasing their source, but the bad structure remains.
