That would make about 0.5% rate of utilization -- I gather 
in the general Web where MAMA collects its data. This is
not exactly impressive if MQ have been available long
before the emergence of the iPhone, but perhaps this 
just means that MQ are not very useful for desktops.

This is not exactly what I meant, rather I observed that
many examples of CSS media queries seemed 
primarily intended for the iPhone _at this point in time_
(probably because of the popularity of the iPhone).

Correct. 

Remember that the discussion started when someone
suggested mentioning CSS MQ in "3.6.2 Use Client-side 
Capability Detection for Dynamic Device State"

What I was hinting at was that for truly dynamic
capability handling, CSS MQ are probably insufficient by 
themselves and require other features (such as JavaScript,
Viewport, etc). The only example given that actually deals
with dynamic capability handling (screen orientation) must
also rely upon viewport. Just an observation, not the final 
word.

For quite some time now, far-eastern manufacturers 
(Korea and Japan) have been shipping phones with
subsantially higher pixel counts than the iPhone or
anything available in European/USA markets. 480x854 
seems to have become typical for DoCoMo and Softbank.

I am not thrilled by this approach...

Yes, and this is why I argue that a best practice must be
based on techniques that
a) are sufficiently widely available;
b) demonstrably "work", i.e. sufficiently solid experience
about them, and how and when to best apply them is
available;
(b) being more important than (a).
