MobileMe is a service that keeps all your contacts, calendar and emails synced between your Mac's, PC's and iPhones.  You never have to use any cables.  If you make a change on one, it changes the data on all the others.

Previously, you would have to purchase an 'exchange server' for about $2500 to do this.  Now, Apple offers this for $100/year -- and it WORKS.  We use this to keep all of our technicians and office computers and iPhones and Android phones up to date!

You can get a free trial at www.me.com.
