I echo what's been said. Syncing was wildly inconsistent at the outset, but has been working beautifully for quite some time now.

My wife and I sync contacts and calendars across our two Macs and two iPhones. It works perfectly now.

And I second what was said about buying it through Amazon. No reason to pay the full freight through Apple, when you can buy a perfectly legit license via Amazon for quite a bit less.
