Dear Tracy

>>A good example of a zero opportunity cost is a free good which is available without the use of resources such as 'air.'<<

If there is no resource use, there is indeed no opportunity cost- not "zero" but NULL.

FWIW I responded to the doomsayers in 1997 when "VFP was dead" and Java was the then Golden Child. In business terms that was a serious failure. I'm not going to make that mistake again, if I move the company to a new tool it will be based on more than slogans and promises. I want to see established success stories where "the move" has generated a measurable business benefit. Articles by people who make a living writing articles are interesting but not enough. "Technically" I'm as impressed with dotNET as I was with Java but that isn't enough this time.

The excellent book "The House of God" established "Masterly Inactivity" as a viable option in many cases. In other words, you don't have to respond to every cue, sometimes "masterly inactivity" is the best option. Well, "masterly inactivity" seems the most sensible strategy to me at this time. The House of God also said "when things go really bad, the first thing to do is take your own pulse." Some people here might like to to consider that.
