>> His mother didn't make the deal with IBM (in fact Ballmer was arguably most instrumental in the nuanced legal structure that gave Microsoft its position) Just for the sake of discussion: if his mother and her relation to the IBM top executive had a critical part in IBM's biggest business mistake ever - doesn't it make sense that they won't want to share those details ?
Quotation needed about mother's involvement. The story that I've read was that IBM had the hardware but didn't think they could make software on time so they went shopping for the OS. First they went to Digital Research who didn't want to do it. Microsoft jumped in and promised to deliver what would become MS-DOS. The rest is history. In no way was Gate's mother instrumental in the process. Citation: http://forwardth…
That does not mean she interfered. It's just a reminder that we should be careful about blindly accepting published accounts of events where the full details are only known by a small number of people all with their own agendas. This of course applies to everything.
