Just because it sells better doesn't mean it's better.
Refer to the part of the post that you seemed to have conveniently ignored.
There's more than money involved in proving what's considerably better, such as the user experience (perhaps the most important) and the iPhone has done an impressive job there.
By the end of the day... The real number would be ..... $!
There are endless list of "iPhone killer" with big numbers & figures ... But what happened to all of them?!
People speak with their $ ... & customer satisfactions for the iPhone.
Enough said.
