"To announce that there must be no criticism of the President,
or that we are to stand by the President, right or wrong,
is not only unpatriotic and servile, but is morally treasonable
to the American public."--Theodore Roosevelt, May 7, 1918

Thinking of buying a new Digital Camera? Here are 10 important things

Tip #1: Film has more resolution and more
effective pixels + doesn't suffer from nyquist
limitations and can utilize better optics.

The rest is OT...

Harry Nyquist would be offended... ;-)

Of course film suffers from Nyquist limitations. However, from that point of
view, the sampling rate is much higher with film than with present-day
digital camerae, and the sampling rate is more random, so that obvious
effects, such as moire patterns, are less noticeable.

I usually use the term "pragmatically," as in film
pragmatically doesn't suffer from "digital's"
nyquist limitations. But I guess one can split fine
hairs and say Nyquist applies to everything. The fact
though is most digital cameras can't capture those fine
hairs because film (depending on granularity/resolving
power) has so vastly higher a sampling rate when compared
to digital you have no need to dumb down typically used
optics or otherwise reduce the scene signal frequencies
to prevent moire and artifacting.
