Do you work on a team? Or in a job were you need to have an audit trail for your work? Commit messaged and many other features of Git like branching and tags are indespensible for sharing and collaborating on code.
Versioned files systems, including Apple's Time Machine and Dropbox's version history, have no extra UI to save versions. A small, short-lived project with at most a few collaborators (eg, working on a small scientific paper) might find those more useful than git or other VCS.
I would not mind something simple. I find the arguments, flags, whatever in git to be rather opaque. That, coupled with the lack of need for its features, have not thrilled me.
It seems to be pretty effective if you have tons of programmers working on a single project, but at the bottom end of the scale, I find it baffling.
(I know, technically, altering commits creates new commits in Git, but it comes to the same thing.)
