I disagree. The 68k architecture WAS better than the pre-386 architecture, but
the 386 and up architectures blow the 68k out of the water when it comes to
memory management. With a '386, you can run multiple foriegn operating systems
AT THE SAME TIME. We are NOT talking emulation, but TRUE multiple operating
systems co-existing. That's how the Sun 386i does their DOS compatibility. Just
assign a chunk of memory, and away you go.

I don't buy this either, the 68k family is supposed to be upward compatible, at
least as far as the opcodes go.

Both processors have their plusses and minuses. It's all a matter of opinion.
No more flame wars please, lets get to serious computing issues.
