Well I couldn't care less about going commercial, so the extra hassle of developping for mobile platforms is just not worth it for me. Doing this is my hobby, I don't intend to live off of it, I don't need the extra money quite that much. I'd rather sacrifice a few dollars here and there to do more of what I like the way I like at the pace I like and less stuff I don't like such as publicity, publishing deals, dealing with customers, etc. Besides I don't even own a mobile device to test it out, so it'd be really troublesome.
