true, you don't, unless you are making *very* huge prints.

for an 8x10" print @ 300 ppi (generally considered 'tack sharp'), you
only need 7.2 megapixels.

that's a bit of a straw man. if you are going to be viewing the
pictures 'at night', i.e., in dim lighting, you won't be able to see
the colours so you don't need to capture them. use a b/w sensor and
reduce the storage for the images.

Do manufacturers tell you if a sensor is back-illuminated? For
example, is the Canon G11 back-illuminated?
