sorry, but i have to disagree...
most cellphone users don't even know that there is such a thing smartphone, dumb phone thing... you will be surprise, how people react when you present them with some smartphone applications... the thing is, smartphone is for everyone, either they are fully using its capabilities or not, it is just a matter of educating the user how to use it and if they can actually afford it or are willing to put that x amount of money for "just a phone"...
although some people will still use a "dumb" phone, just because they like the look of it or the simplicity of the menu system, or in your case the camera adn are happy with the java apps... but bottom line, smartphone is for everyone and it has gone mainstream and no longer just for the geeks and the tech savvy professionals...
and the gap between the dumb and smartphone is still wide and just got wider even, coz of N95...
