A tiny bit more
A few comments.
1) IBM was STRONGLY urged to skip the 286 and create a true 32 bit, 386 version of OS/2. Even Microsoft was strongly pushing IBM in this direction. IBM's resistance to do so was a major contributor to the split between IBM and Microsoft.
2) The MicroChannel was better than the ISA bus. The problem was it was not good enough for the future. The PC evolution was moving towards faster graphics and network (100 mbps) connectivity. The MicroChannel, even 3 generations into the future did not have the bandwidth to meet these needs. The industry evolved to the PCI interface. As an interesting historical coincidence, PCI uses the same type of connectors as did the MicroChannel. And the PCI interface found its way into other IBM systems.
3) The IBM PC was inferior to Apple's products. The PC became more successful because a new industry and IBM's customers worked together to make it successful. (Steve Job - The Lost Interview) In 1987 IBM turned a deaf ear to the industry and its customers. When IBM stopped listening its fortunes turned. This culture took over the whole company and was a major factor in the company almost going out of business in the 1990's.
