First, there is no "all my clients." There is the iPhone syncing with MobileMe and iTunes. That's it. I have no other devices and no other software.

Second, I don't keep track of the Syncing closely, but I use OmniFocus every day, and it sure seems like at least once a day that spinny sync icon stops spinning while I'm working, which I assume means a sync has completed. Certainly every week.
