I use an iMac at home and a laptop when travelling, so before and after each trip, I need to sync the machines. It works beautifully for this. The instructions can be a bit intimidating, but I haven't need to customize it much. I simply update several main folders (Docs, Desktop, etc.), and it works without a hitch. I haven't used it over a network, so I can't speak to that. But for my purposes, it's a dream.
