I agree and like these specific classes. My own personal list is ordered by EIN 
and your classes accord with how I think about the devices. I will present this 
perspective in a future article. I thought it more important to most of my 
readers to look at form factor first of all. The article was in part written to 
answer some specific questions people have asked me face-to-face.

It would be good to have some idea what the self-noise of the built-in mics is, 
apart from the external pre-amp stage. But I can't see any way of measuring 
that short of surgery on the electronics.
