I have the same problem. I wouldn't mind dropping all my @me addresses for @iCloud addresses instead.
Your @me.com address will continue to work. Anybody sending an email to you using that address will arrive in your Inbox.
You could configure your email client to use @icloud.com address instead.
This transition is the same as when .Mac switched to MobileMe and they introduced @me.com addresses. All @mac.com addresses continued to work, and is what I've used for the past 10+ years.
