I have Chronosync and I love it. Right now, I only use it to copy my documents to my iDisk documents so I won't ever forget anything when school starts back up again. I plan on getting the 2010 MP and have tested Chronosync out when keeping two folders in sync over the network. I tried it with my MBP to my Mac Mini over wifi and it worked fine. With Chronosync, you can set a schedule to it, as you probably know. If a scheduled sync tries to happen and you are not on the network, it will play a sound meaning there was an error. I don't get popups, which is nice cause those can be annoying. And if I remember correctly, Chronosync will automatically sign in as a specific user if you have the password saved in your keychain, which is also nice. So overall, yes, I would recommend Chronosync.
