If I understand MS business model correctly VFP-involved costs are mostly payroll to VFP-team members. I wish they have very good salaries, but still given limited number of people the costs could be very low (and it's still exaggeration) comparing with MS revenues.

>Revenue may or maynot become income. Depends on costs. IMO, that's what happened with VFP. The costs outweighed the revenue.

>>In general, current revenues is future income, though many exceptions may apply. VFP was a very poor product for MS on both fronts; it gave too much power to middlemen, i.e. to us.
