How do you choose an ARM family

How do I go about picking an architecture ? My first thoughts suggested Cortex M3 but the more I look into it the less sure I am.

Obviously I don't to go to the trouble of learning a new technology only to find that I've made a bad processor choice (ie nearly end of line). I've spent many hours looking at many websites and have yet to find any high-level stuff on choosing my first ARM device.

If there's one thing wrong with ARM its the almost infinite number of devices

I'm an embedded developer wanting to undertake my first ARM project, so I'm completely new to the ARM architecture. I want a low power device with serial, USB and some ADC channels.

    and you cannot provide any examples of such libraries that would allow its licensees to use on _any_ processor.

    it is a theoretical possibility and practical impossibility.

    unfortunately, we live in a world that "should" has no value. "Per should be a billionaire" doesn't buy a $0.49 burger at McDonald's, :).
