Pixel density is a chimera. Sensor size at the current density is a
much better solution. Much more expensive however. I'm much too tired
and lazy to do the math. You're still limited by the sensor. Which
doesn't invalidate my assertion. Unless you expect better results with
in camera processing to remove the noise.

it matters because sensor density is still rising. until we get about
20 megapixels in DSLR, we've still got a ways to go yet. at that
point, all but the best lenses will be the limiting factor. even now,
on the *istD, most of the consumer grade lenses aren't up to what the
sensor can record.

I too have held a Canon 70-200L f4. I was not overly impressed. It
may be a better optic, it may not be, but does it matter? After all
the limiting factor these days is the resolving power of the sensor
in your camera. The SMC-P F 70-210 is already theoretically overkill
for the sensor in the *ist-D and assuming that the Canon is at best a
D20 it should be very hard to see any difference in resolving power
based on the which lens is used. I see constant F stop envy at work
here.
