While much of the system looks pretty competitive (of course all such feature
comparison tables yet created are designed to favor the choice of their
creators), I think this is a big mistake.  Any new 32 bit machine with a
16-bit only expansion bus isn't going to go over well.  New Amigas and Macs,
along with an ever-increasing number of PCs, are providing multiple 32 bit
slots.  You can always plan to build everything in, but even Apple has had to
admit that doesn't work very well.  The choice of an industry standard bus
could be a good one, especially now that VME supports chips are dense enough
that you could have something other than the VME support logic in the space
of a 3U card.  But most of the new VME cards on the market are full 32 bit 
6U and 9U cards; the simple I/O type things most desktop computer buses are
normally doing are generally handled by VME mezzanine buses these days.  But
who knows, Apple was successful in creating a desktop version of NuBus.
