You made people perceive it as a phone. That is not their fault. if you want it NOT to be called a phone AT ALL. you don't advertise the phone functionality AT ALL. You don't release a work in progress to mainstream users and make that an excuse for everything. the moment it went into a nokia shop. it became a consumer device. not developer.
That does not permit you or anyone from saying that asking for it, is in excusable. It's called Feedback.
