1/ IBM’s OS/2 vs Microsoft's Windows was an important period in the history of PCs and computing. People who were not around then too often have a false view of what happened (e.g. MSFT head fake) and even people who were there can have different recollections (Rashomon effects).

This looks quite a bit like Microsoft’s take. Having been there as a customer and an IBM employee (admittedly without any sort of inside access), I remember things differently

OS/2 1.x sucked, but 2.x and 3.0/Warp were much, much better products than Windows at that time. In fact (after I’d left IBM), I used it to build Windows apps because it was a vastly superior environment

But IBM was a complete disaster in marketing to end users, at which MS excelled. The better product didn’t stand a chance.

Gates: "I remember change request #221: “Remove fonts from product. Reason: Enhancement to product’s substance. Someone at IBM didn’t want the PC operating system to offer multiple typefaces because a particular IBM mainframe printer couldn’t handle them.”
