If you have a smartphone, chances are your account to whatever is already compromised by the ability to reset via email, unless you are good about signing out of your email application. So a phone solution sounds like a pretty good solution, since it's not any worse than the current situation. However, a fair number of people still have a 10 cent/message SMS plan, and would be unhappy if they had to start paying $1+ a day to log into all their accounts, so using SMS seems less than ideal in that respect.
