In that era, I was a user of OS/2, originally the successor to WinDos by both IBM and Microsoft (MS). As a stable platform, it had it in spades and was virus resistant as well. Problem was that IBM lost interest and MS saw the opportunity to ‘rule’ the operating system niche and went for Win95 and its successors.
While IBM was still selling OS/2, the rumor was that MS would send out people trained to crash the system so that the displays would always show malfunctions. Easy to do for almost any OS of the time, the difference was that this niche was essential for MS while a sideline for IBM. (MS was committed like a pig furnishing bacon for breakfast, IBM was dedicated like a hen laying the eggs!).
History has spoken but the irony is that MS is now the 800 pound behemoth that can find little success and no credit for their work. Windows 8 appears to be less than stellar in its uptake rate and so the flash belongs to that MS Office and Xbox cash cows. Even Apple now finds itself fighting Samsung and Google as the current beleaguered “King of the Hill”. Times do change but cycles will reappear!
FYI: As an IT guy for many years, I worked almost exclusively in the WinDos world from the 80s onward. In 2005, I received a Mac Powerbook from my Mac ‘evangelist’ brother and have never looked back. I do use Parallels to run certain Windows specific software very successfully on my iMac, but I am almost entirely Mac and iOS in my life now.
