In the case of the portable, *not* going with the CMOS 68000 left them with
*no* processor, given constraints of power consumption.  They could have
done it, maybe, but you'd kiss 8hrs+/charge goodbye.

I agree, S7 isn't going to buy *me* that much...at least as long as my Mac+'s
are still running.  I can live with it.  (And I don't think that the Portable
is obsolete on intro.)  But if you *don't* have other major constraints, such
as power consumption, there seems to be little reason for not putting a
68020/030 in newer machines, other than the obvious one of cost.  Competition
with current higher-end machines shouldn't be a problem, particularly if you
restrict expandability of the base-level machine.

Since you also need to get a 68851 with your '020 to get virtual memory (and
Motorola may be dumping the '851 completely), you could make a case for going
directly to the '030 and ignoring the '020 completely.
