Sorry for the possible so simple answers to my questions. Time Machine... How well does it work and is everyone using it effectively? In other words, aren't there other backup applications that is comparable? In addition, is it something that is crucial? I can see the use of it for I back up things manually to my external drive but having it all automated seems pretty cool. yes, I could've done it with the other backup applications if I had the time to set it up. This is my first mac.
