Yes the HP-48SX has bugs, although the only one of any consequence that we
know about is the 8x8 matrix inversion bug that Dan Allen alluded to.  (By
the way, this bug only applies to the INV command; you can still invert a
matrix of any size by dividing it into an identity matrix).

HP's policy regarding bugs in early releases is (remains) to make the customer
happy.  If you find that a software bug seriously impairs your use of the
calculator, you can have it repaired under warranty.  Most people find
that early release bugs turn out to be a minor problem, and never need to
have any upgrade.

This is a different situation that that of the 28C vs 28S.  HP viewed that
change as a model change (there was M$ worth of R&D involved) rather than
a software upgrade.  Unfortunately, customers didn't see it that way because
of the near-identical appearance and same price of the two, so there was
a lot of bad feelings on the outside and regret on the inside.
