Very interesting article. I hadn't realized that Microsoft strategy of developing their market not by the merits of they product but by lock-in to use business programs (and also games and such) went back so far. Also it's great to finally learn what "UMB" stands for in "DOS=HIGH,UMB". Never felt right to add that option without knowing its meaning :-).
