Mine works, and the day it stops, is the day I start using my own domain name as my main email address.
My .mac account is my apple id, my main email address, I cannot fathom that apple will stop it at this point
I agree fully with you. I was thinking about this again this morning. If apple did stop allowing people that have had an @mac.com email address from using it and forced them to use @me.com then this would be a nail in the coffin for apple in the email market.
You just wouldn't be able to trust that you wouldn't have to change your email every few years, for example if they wanted to introduce @icloud.com or something similar with all the fun and games that that would involve in contacting people and updating your address etc.
I just can't see gmail, yahoo, or hotmail saying oh by the way you have to change your address that you have had for 10 years or so..sorry.
I have my own domain for my business but use apple mail and other accounts for some not unimportant things. Surely you must be able to trust that an email address will last almost indefinately
