I already mentioned the study by Erkko Anttila, “Open Source Software and Impact on Competitiveness: Case Study” from Helsinki University of Technology, where the author analysed the degree of reuse done by Nokia in the Maemo platform and by Apple in OSX. I have done a little experiment on my own, by asking IGEL (to which I would like to express my thanks for the courtesy and help) for the source code of their thin client line, and through inspecting the source code of the published Palm source code (available here). Of course it is not possible to inspect the code for the proprietary parts of both platforms; but through some unscientific drill-down in the binaries for IGEL, and some back of the envelope calculation for Palm I believe that the proprietary parts are less than 10% in both cases (for IGEL, less than 5% – there is a higher uncertainty for Palm).
