Sure, but who uses iCloud as their primary email provider? I certainly don't trust Apple to get it right, given their experiences with internet services. They've already changed people's email addresses as least twice, which is beyond uncool (mac.com -> me.com -> icloud.com). Unlike your username to their services, your email address is tied into all sorts of other third-party services (not to mention address books) and is incredibly painful to update.
