Sorry, I'm not an expert, but I don't buy any of those reasons.
I feel the same dissapointment as Chuck McManis does.  I don't
have space to the side of my Amiga.  The buss cable could be shielded.
It would only have to be about 4 inches long.  I don't believe that
would screw up the timing (I understand that a signal propagates
more than 12 inches in a nano-second, so 4 inches would effect
timing by 1/3 nano-second or so --  can't be that critical --
the CPU isn't going all *that* fast afterall).

The FCC isn't going to care if the thing
sits on top, under, behind, or to the side.  The FCC does care about
noise and like I said the bus cable could be shielded.

I think the real reason is that they came up with the name,
then later realized they couldn't very well put a "side-car"
on top.  That plus the few extra bucks it would
cost to have 4 inches of shielded cable (maybe $20 ?).

OK all you engineers, go ahead and flame me about what
4 inches can do.
