I would love to see SMS disappear. The two things I think are holding it back: - Phone's default ringtones for SMS are much more notable than the email alert. Change the defaults on phones so that it's more obvious when an email arrives and people will be more likely to use it. - Less spam. People are generally confident that SMS messages are sent from someone they know, so they check them immediately. If email had less spam, people would be more interested when email arrives. Fix these two things and I think there will be broader appeal to email as a replacement to SMS.
