For syncing, you're gonna want to get a MOBILME account. It's a $100/yr, APPLE email, online storage, website, account.
It keeps all of my cpu's sync'd with almost no issue. So my two lap tops, my two desktops and my Iphone, all share information like:
Calendar, Contacts, Email, Bookmarks for web browsing, seamlessly.
A change on one system or update will automatically update all the others. It's actually brilliant. And you don't need to ever sync your iphone to a computer tethered unless you are syncing music or movies, etc.
change a contact, make an appointment, browse your email, on any system and it will update all your other devices.
A Mobileme account will give you your MAC email address which will be a "me" or "mac" if you have had it for a while, or both.. For example:
[email protected]
You're also going to want to use:
MAC MAIL
Ical
and ADDRESS BOOK.
They system is the best it's ever been and I've never had a blackberry or a program like Entourage that works as seamlessly as MOBILME. Of course though, you do have to use the proprietary MAC software for it to work..
But the MAC software works remarkably well.
