> Upgrading the OS to a major version without worrying if I'll be able to boot next time.

Yeah, well my friend's Intel Mac mini got bricked when he updated from Big Sur to Monterey in the first week after release. Needed to send it to Apple service. IMO Mac updates are almost as broken nowadays as Linux updates were 7+ years ago when I daily driven it.

I also upgraded my Thinkpad X220 from Windows 7 to Windows 10 when the update showed in my system, and everything worked without any reinstall since then.
