It's not always as easy as dropping support for older devices/OSes. When you have to support older systems (for client requirements, as an example), it goes from a "tiny bit of extra work" to "a tiny bit of work and a whole lot of extra testing". Just adding a single different type of device (i.e. supporting Blackberry Bold and Storm) almost adds twice the testing effort. I'm not trying to say that developing for resolution independence is extremely difficult... but it's no walk in the park; it takes time. You truly have to ensure that your application can run on a wide gamut of devices and that the user can interact with it appropriately.
