Well, all the main breakthroughs that Canon mentions
with the CMOS for the D30 are functions (noise
reduction, programmable gain, etc) that are
implemented on the chip. That is only (reasonable)
possible with CMOS sensors. Clearly this is an
improvement of the CMOS sensor itself (and there is
still much more potential) and that is what I am
talking about. Off-the-chip postprocessing does
improve images even more but that is also done on
CCDs. I agree with Mr. Bill that CCDs are better for
astronomy, and might have a small edge in still
photography (and worse for very high fps). But the
latest chips are extremly close to CCDs (for still
cameras) and they are improving faster then CCDs... I
wonder about the specs of Canon's professional digital
camera!!!

PS: Did you know that one of the space observatories
out in space there uses a CMOS for important measurements...
