Probably you don't understand that if the community is here is due to Nokia's devices first of all.

But I agree: the recent shift in the events will make the developers interested in developing for Linux platform jump on Samsung's band-wagon in the next 3-5 years, as soon as the current N900-N950 and N9 devices will become obsolete.
And whenever this shift will happen good old Nokia will be gone for good because the dev community around here is the one that is currently making 90% of the work supporting these beautiful devices.
