Executor runs 68k based Mac programs on the x86 architecture *much*
faster than SoftWindows runs runs x86 based programs on the PPC
architecture.  I tossed in the erroneous comparison because I thought
that would be a good illustration of Executor's speed that many
readers would relate to.  Of course since it was incorrect, it didn't
make a good illustration at all, which is why I was so quick to
retract the statement.

My point wasn't that Executor is better than SoftWindows, only that
they each have strengths and weaknesses.  Although the specifics of my
speed claim was not correct, there really is a substantial difference
in speed of the two programs (it's much easier to emulate a 68k on an
x86 than vice versa).  Occasionally the speed differences will matter
to the potential end-user, but more often than not it won't matter at
all, since more often than not people buying Executor will already
have a PC (they're pretty common), or will be buying one for some
other reason.

Only a relatively few number of people are going to buy a new machine
*and* want to be able to run some apps from both universes *and* are
going to use the differences in the two emulators to decide which
machine to buy.
