hi, maybe I've got a nice solution for your problem. You could make an e-mail account at mail.com (you get 10Mbs here) or yahoo.com or at another webbased e-mail site and then forward your e-mail to the new account (at apple.com) (you have that forward setup on a mac).
If you do this, you can check your e-mail whenever you like on every computer and still use your mac.com account.
