For example, if you want to try Evolution (or some other local
application with local data), you must download your mail, and you
will try to write a message to send, just so you can discover that the
editor of evolution is worse than the previous, and when you use undo
(ctrl + z) undo does not do "undo" but something else and dirty your
text (this, unfortunately, is a real problem that happens even now as
I write this message).
At that point, if you do a revert to f21, you lose all messages that
you have downloaded and all work that you have done in the meantime on
your machine. At this point it is too late.
If your mail is handled through an IMAP server (rather than POP), then
this wouldn't be the case. Your mails are stored on the server, and
your mail program browses them. If you want to test a mail client, or
have to put up with continually replacing your OS installation, it's the
best way to go about it.
As for the rest of your work, there are various ways of dealing with
that. There's the backup and restore technique. Or, keep /home as a
separate partition, so that you can re-install around it (still make a
backup though, just hope you're lucky enough to not have to make use of
it). Or you can keep your files in a separate server, which could be
another computer, or just a networked drive.
These days, it's next to impossible to get by with just one computer.
You almost need another one so you can research, on-line, how to fix up
the other one when it goes doolally. If you're in that position, you
may as well install a long-lived distro on one, and use it as your

All mail to my mailbox is automatically deleted, there is no point trying
to privately email me, I will only read messages posted to the public lists.
George Orwell's '1984' was supposed to be a warning against tyranny, not
a set of instructions for supposedly democratic governments.
