Instead what you do is fail to adapt to a UI paradigm optimized for a handheld. Yes, you're entirely free to not adapt, but there will not be many customers who will prefer your way of interaction (handheld, Linux, GTK, all kind of little checkboxes and cluttered interface with tons of bells and whistles, stylus-optimized, 4"1 screen) instead we are moving towards optimized UI paradigms. That means we say byebye to previous, sub optimal ones.
