AppFresh

AppFresh is a great application for MacOSX that checks your applications, widgets, and preference panes and makes sure that you’re running the latest and greatest by comparing it with what’s stored at iusethis.com. What’s even more interesting is that you can create snapshots of your application and rewind back to another older version if you happen to hate the latest and greatest for whatever reason. Don’t like it, don’t use it. What a great little app that keeps you on top of everything you use. Nice.
