I moved the family email accounts from mac.com to elsewhere (no addresses need changed, because mac.com was just the end location, and mail was forwarded there from elsewhere), because Apple is going to start charging $100/year for mac.com addresses.
It's really a horrible shame what Apple is doing. There are primarily two types of people who will pay Apple: 1. the person who really wants all these .mac services and is getting a pretty good deal, and 2. the person who, because of reliance on the mac.com address or because of lack of computer ability to change to a different account is essentially forced to pay whatever Apple wants. For the former group, they have no complaints. For the latter, it's classic bait-and-switch.
