You are correct that my technique will tend to wear out the
flash faster than yours.  However, the 32M CF filesystem is
supposed to be used in a production environment.  I would
not expect people to do update frequently.  It is somewhat
similar to what Cisco is doing with their routers, like the
2500/3600.  A complete system is actually contained in just
one file or image.  The flash upgrade should only happen
once in a few months, like maybe twice a year.

In your case, it is different since it is designed to be more
of a "real" development system.  It is always wise to have a
HD for such cases.
