This is a wonderful program and a great asset to Mac Admins. That isn't to say it doesn't have any problems, but they are fairly minor.

I am an Admin at a large University and we use CCC for cloning disk images to all our Macs every semester, hundreds of machines, without issue. Some issues do exist but most are 'rough around the edges' type things. It doesn't return the clearest errors at times and attempting to cancel a clone is usually futile, requiring a force-quit. Otherwise it is very handy. I hope it is updated for the new Intel machines, Leopard, etc.

To the previous two reviewers give me a break. If you don't know that your target drive is too small to fit your data then perhaps you shouldn't be tinkering with your Mac....get a professional to do it for you. This program does serious stuff and is *not* for the clueless as you could royally screw up a system using it without knowing what you're doing.
