Should Apple give in to market demands?

These days I feel there are many who believe Apple should listen to so-called market demand and release a bigger screened phone, NFC support, wireless charging etc.

Now I definitely think that companies should listen to user feedback within reason, but was the iPhone/iOS platform a culmination of user feedback?

From what I remember, before the iPhone release there were a lot of on-screen click wheel based UI concepts. Just imagine if Apple had listened to those.
