We work around this problem with our own XML runtime parsed UI Library. It lets us have a set of layout files for each screen size of the application. Since we've implemented it for almost every platform out there, it means I'm mostly writing application logic. (Which has it's own set of pitfalls) As much as I hate buzzwords, it really helps to take an MVC approach to mobile development. Different screensizes and input methods just require different views on top of the application logic.
