The abstraction is of course a necessity when it comes to developing one app to run on lots of different devices. However, just abstracting the UI and phone stack doesn't at all require something on the order of a VM. Apple, Trolltech, and others (not sure about GTK) are have device-independent app frameworks written in compiled languages (ObjC & C++, respectively), so there isn't really any upside to having a VM, only extra overhead.
