The unexplained deletion of all my MobileMe contacts has happened to me many times -- every few months in fact -- and I have never been able to figure out why. Along with backups, I have set my Mac to warn me if more than 5% of my information is to be changed. This has allowed me to cancel the sync, quickly do an Address Book backup, allow the sync to proceed, and then reimport from the backup. I then reset my sync data, replacing the info on the server, so that the contacts repropogate to my other devices. If anyone has additional information about why this happens I'd love to hear it.
