Srsly, which is how most people in other countries have to pay for it since there's no carrier subsidy.
would u still buy it?????
People do it all the time (those who upgrade early, etc.) I've purchased unsubsidized twice, though was more forced to that wanting to. Also remember that $600 isn't a ton of money to some people.
In the US we don't get a discount on the monthly charges if we buy the phone out right.
