From the .Me page, info re: email-only accounts:
Can I purchase additional Email Only accounts?
Email Only accounts have been discontinued. Only existing Email Only accounts may still be renewed. If you would like to share your MobileMe account with other family members, you may purchase a Family Pack upgrade in the Account section of me.com at any time during your subscription.
Current email-only accounts do have push email - something I did not notice before:
I have an Email Only account. How does that work now?
MobileMe will now push your email over the air to your iPhone and iPod touch, and you can also access your email at me.com and on your Mac and Windows PC. However, your Address Book data will not be synced.
Quite pleased I got an account for the wife before email-only accounts were stopped!
