non-smart is a non-starter these days. They all have processors and run operating systems of varying complexity. With the free availability of proper smartphone operating systems, you can expect more and more of these "non-smart" phones to start coming equipped with operating systems like Android. The big question is why would you want to put the resources into creating and maintaining your own proprietary firmware rather than using what is freely available and better than anything on which you can justify the development cost?
