Sometimes (rarely) I plan to revise a long email and want the drafts versioned. I also keep config files (e.g. .muttrc) and some longer reports in the same parent directory (letters of recommendation, short essays, etc) and I want those files versioned for sure. rsync might run into problems if you dl new messages before syncing (which I do all the time) but unison should work fine if you don't care about versioning.
