Time Machine

I have been keen to try Time Machine, and I have been on the lookout for a reasonable deal on an a backup drive. Today i found one at Circuit City. I found a Western Digital MyBook 500GB drive for $99.95. I snapped it up and headed home. There was nothing to setting it up and now my Mac is backed up automatically. I am happy with this process. As a fairly non-technical person, this seems a quick and complete backup solution. I was doing some manual backups to my other external drive, my portable one, but I have some peace of mind knowing that all my stuff is secure.
