- 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.
