What I heard was something similar to that story.............and it was that Microsoft pressured gateway, that if they were to invest into another computer platform with OS, that Microsoft will pull licencing Windows to Gateway..........incidentally Microsoft also Purchased COREL right when COREL was about to make a Deal with Amiga to create apps or a Linux/AmigaOS.
I don't know if this is true....but is what I heard.........although the details are not exactly as I heard/read them.
But I partially believe this....Microsoft Purchased Blue Ribbon Sound Works when they were writing software for Amiga.
