I just wanted to do a sync after several days, and iSync suddenly wants to copy all my appointments from the organizer to my Mac - without me making a single change to any of these appointments on the organizer. That's absolutely ridiculous. And you can't even tell from the message that mentions 132 new objects which objects those actually are and which device they're coming from - at first I suspected the sync was coming from my phone.
Why can't Apple get synchronization right and why do they pester us with this pathetic pile of junk?
Sure, it's nice that you can synchronize all kinds of devices with iSync and even sync multiple devices at once. But that's completely useless if synchronization regularly duplicates and scrambles your data.
