What is biting my ass, Bill, is my bloody cumbersome English. Let's see
if I can hit the target from the second try.
The measured DR is useless because it is theoretical. The measurements
were taken in controlled environment by people who specialize in doing
such measurements.
In reality the metering is not always spot on, and not because of a
camera, or actually only partly because of a camera, but also because of
a human error. Human being me here.
Further, in my area of interest :-), contrast is usually extreme. Thus
even a minor error is what it is - an error. Now, the more DR I have -
the more tolerance/leeway for correction I am given.
I don't pretend to be extremely accurate or well versed in terms of
using my camera. I usually set it to P-mode, dial in some -0.7Ev
correction and go on shooting. I try to deal with tonality of my
pictures in post.
So, I much rather have wider DR than more MP or more focus points, that
all. Like I said - it is subjective.
Oh, and like Larry pointed out - the more DR I have at base ISO, the
more DR am I going to have at higher ISOs...
Does it make sense now? Do I sound pessimistic?

Bill, it is purely subjective. I have suffered enough grief from K-7's
sensor and frankly, the way Pentax treats highlights in their RAW
files seems to be rather unforgiving compared with those of Ricoh GXR
(any module with 12MP sensor). So, I don't want to take any chances.
Boris, it isn't subjective at all. This is one of those areas where DXO
is a good resource.

Look at the DR. The K7 is 10.6 EV, the K5 is 14.1EV, the Ricoh GR is
13.5EV. They don't have the K3 tested yet, but I'm thinking it will
probably place very close to the GR, based on what I've see coming off
the camera.
We know that the Samsung sensors used in the K20 and K7 never performed
the way they were supposed to, if they had, it's doubtful that Pentax
would have moved to Sony sensors in subsequent models.
This is one of those times when being a professional pessimist is biting
your ass.
