No problem there, Jim.  I understand it's not a pure apples to apples
comparison, although I would argue for a Jonathon to Macintosh comparison
vs. an apples/oranges one.

I am not a manager, and I don't participate in system acquisition
decision-making, so I don't really know the market.  And I certainly won't
pretend to know the value / extra cost ratio of the improved MTBF/service
type/tolerances, but the 900% premium seems steep to me.
