Luminous Landscape has a page in which the virtues of variable ISO

There are a couple of very nice shots with the Canon EOS1Ds and a
couple of long Canon lenses with telextender.

This is one of the two or three truly "killer" advantages DSLRs have.
Imagine in some future time, you set the shutter speed and aperture
exactly the way you want to for the perfect mix of DOF and speed to
capture the motion the "right" way. Then the camera set the ISO to
make it happen. In ideal case, it would be noise-less from ISO 1 to
ISO 6400. Yummmmm....

The Canon actually has automatic ISO bracketing. Reichman's estimate of
noise with the 11 megapixel chip at ISO 800 is about the same as the
grain/noise on a scan of an ISO 100 film. Pricey camera though. And a 1
Gigabyte micro drive hold about the same number of images as two rolls
of film.
