I have an old ThinkPad X200s that I turn on from time to time. I keep a fedora installed and updated just in case, and since I'm there, i also sync my nextcloud stuff.

E-mails using claws-mail are not a problem. It generally runs fast enough until I open firefox and web stuff in general.

Claws Mail on an old Atom is a lot faster than webmail on pretty much anything else. This probably illustrates best the difference between the two approaches.

I remember times when webmail basically meant squirrel mail. It was fast over an 56k modem, but desktop was always better.
