Well, dpad is pretty much necessary for most dynamic games, and most Nokia phones have dpads. So, by removing dpad you close off whole bunch of use cases at the advantage of not having 4 stupid little buttons. It is not like not having a joystick in your car, but more akin to not having a steering wheel.

Best practice is to take the entire population of potential consumers - certainly including the current users - and to test amongst them as a whole.
It is not physically possible to test on more than a few thousand people at a time. Furthermore, all you can expect from such a test is a bunch of filled out questionnaires of "like / don't like" kind. By comparison, here you have got a few hundred (not few thousand) people who handled your devices and know their strong and weak sides.
