Over on the Minismft thread, someone mentioned DEC. In the 90s, I worked at a (no longer existing) telecommunications company (M__) and helped support an application originally running on VMS. With much pain, we ported that application to a unix based system. Even as we did the port, we would never have guessed that DEC would crater so quickly. It was particularly painful because DEC had facilities here in Colorado Springs, and I knew people who worked for them. I also worked for a while at IBM, before the first voluntary RIFs (followed by involuntary RIFs), which is probably why I am fascinated by the current Microsoft story. I have personal experience of how fast large technological companies can go down the tubes. Microsoft has a lot of cash on hand. My own guess is that Ballmer's departure is the board's response to financial underpinnings that are even worse than the most recent earnings report indicates. Cash on hand can be used to cover a lot of financial shortcomings. For a while, anyway, as Enron taught us.
