Ubuntu on Windows

I went to one of IBM's dog-and-pony shows when OS/2 warp was released, and walked out knowing it was doomed. TCP/IP was still an extra cost add-on at just the time that the Internet was taking off commercially, developer tools were expensive and they had no outreach program to attract new ones, and they didn't have compatibility with windows 95 apps. So clearly there was going to be no app ecosystem and no pool of consumer users to attract developers, meaning it was going to wither in decreasingly small commercial verticals. Microsoft made much smarter management and marketing decisions even if you neglected their predatory monopolist tactics.
