With an SLR you
can choose and later upgrade your optics. SLR sensors are bigger and so each
pixel is bigger. This allows greater light sensitivity and lower signal to
noise ratio - which adds up to higher picture quality and in particular
allows the higher shutter speeds necessary to get a sharp image with a
longer lens.

Um, shouldn't that be HIGHER signal to noise ratio?
