I still have a "
@me.com". I use it for iCloud and signing up for anything that I will use primarily on my phone. I didn't get a MacBook until 2014, but I've had an iPhone since 2012 and an iPod Touch a couple of years before that. My iTunes account is under a "@aol.com" though. I don't think that address is even officially active. They need to give us the ability to change iTunes account emails.
I believe you are now able to change your Apple ID email at
https://appleid.apple.com/ now, as long as your primary email is not already set to an @mac.com,
@me.com, or @icloud.com address. If you mean you have two completely separate Apple IDs, not just two emails on one account, then you still cannot merge them, unfortunately.
As for the topic, yes, I do still have my .Mac address and have used it as my primary since I got it with my first Mac back in 2007.
