That's precious!  I'll have to save this post.  Yet another hobbiest who
thinks the world revolves around him.

Windowed versions cost more because it takes extra steps to add the quartz
window, which also forces the ceramic package.  Most importantly, however,
they are more expensive because the volumes are so low.  The windowed parts
were created so that code could be developed for OTP parts without requiring
a new chip for every code tweak.  The volumes are so low because the
software engineer only needs a few during development, then OTP parts are
used for volume production.
