Well, now I'm not too sure this is entirely true.  What about upgradable
motherboards?  Can you add one of Intel's many upgrade chips such as the
one which converts a 486SX to a 486DX?  Can you replace the 486SX chip
with a DX2 chip?  If the answer to either question is yes, then the
486SX may not be a bad investment.  The future brings lower CPU prices
and the upgrade in a couple years might be worth it.  In fact the upgrade
may not be any more expensive in two years than adding a 387 to the 386DX-40.
