1) The instant review *is* representative of the data you
captured ... the JPEG processing is consistent and shifts from what
the RAW file is by a consistent amount, so you can use it as a guide
to what your actual exposure is. The hotspot blinkies are, to me, the
most telling and useful exposure control warning. Histogram is also
useful, just not quite as much so.
2) Instant review, set to 3-5 seconds, allows you to see any glaring
and obvious faults in the composition ... like people's eye's closed
during exposure, etc.
3) Playback review allows you to determine sharpness without leaving
the site so you can re-shoot if needed.
Providing information regards the use of the camera's controls is the
function of the instruction booklet. Informing the public as to how
those controls perform, as well as how the camera performs, is the
function of a review. Neither is intended to tell you how to use
those controls and feedback mechanisms to best intent.
In answer to your second question:
Stay tuned for my best selling book,
"Digital Photography Using the Pentax *ist DS, a Compleat Guide"
I'm only about half joking...

Until
such time as it was clearly explained to me how the review and
histogram
worked, I could not get decent exposures with the istDS. As a
participant
in this group, it was relatively easy for me to get the information
- and
even then it took a while, so my learning curve was slowed, and my
frustration index was a lot higher than it needed to be. However,
most
photographers don't participate in groups such as this one. How
does the
photographer who doesn't have access to this information improve
his or her
photography by relying on what may be considered misinformation
without
someone explaining the situation, or without reading it somewhere.
I've
~never~ seen this mentioned in any review that I can recall
reading, and it
doesn't appear to be in the camera manual either.
