Out of curiosity, what's the difference between the "microprocessor"
type crystals and other crystals? Is it just frequency stability or
is there something more fundamental?

Stuart-

Michael's explanation brought back memories of my teenage years and
home-brew crystal controlled rigs.

A shorter answer is that a microprocessor crystal frequency may not be
critical while a radio crystal frequency may be.

It would be critical if you needed your transmitter to be on an exact
frequency. In your computer, it wouldn't matter much because no one is
listening! The only time it would matter is if the crystal frequency is
used to keep the computer's clock accurate.
