Is there an FAQ on syncing?

[neoelectronaut]

So I'm looking at system preferences and there's alot of stuff there to sync. Some I understand but others I don't. Why would I need to sync, for example, my dock items or my keychains to my iPod Touch?

Can someone explain every option in the Sync preferences tab?

Also, what's the difference between syncing automatically and every day?

Most of the sync options are not for iPhone, but for other Macs. If you have multiple Macs, you can sync dock and keychain items, ect...

Second, syncing automatically does it when there is a change to your calendar, contacts, ect...
