Good critique, VTOLfreak. Again, I see you've done homework. I'm impressed with your breadth of knowledge - again, I think you're really informed.
I did not make it clear that I read your comment not only as a joke, but as flippant and sarcastic - almost mocking. I tried to take it seriously, and so I answered by analyzing what I saw as the comment's premise. If it were a simple joke, I don't think I'd find a reason to respond with a seminar. But good critique- it was a seminar, you're right.

I've gotten a lot of heat from colleagues for my switch from PCs. I find it's not only a personal choice, but also a political one that seems to illicit curt, flippant responses from them. I responded as I do to colleagues. I imagine you understand. Thanks for your clarification. pdX
