However, I am a very happy Super Duper customer. I use it because most of the time my primary computer is a desktop iMac. But when I have a presentation to give, or I’m otherwise going to be out of the office, I use Super Duper to copy my /Users directory to a PowerBook. This ensures I have all of my files (and the different user accounts that I use) with me when I need them. When I get home another Super Duper session back to the iMac and I’m once again current and have all the changes I made while on the road. Because I have to do this somewhat regularly, I use the “changed files only” option to reduce the time it takes; but overall it’s definitely fast enough and very, very convenient.
I know that I’m missing out by using Super Duper as a one trick pony, but it’s a good trick that is essential for my current working style, so I’m happy. If you’re faced with a similar need, I suggest you give it a try.
