Maybe it wasn’t the best something — maybe DR-DOS was better, or whichever flavour you happened to like if you are old enough to remember those days (and yes, I am; thanks for asking), or IBM’s various tries at recapturing its lost glory. But that doesn’t really matter. You may think DOS was bad and Windows was worse, but at least Microsoft stabilized what was a fragmented and chaotic market, and that arguably pushed us further ahead faster. If they hadn’t done it, someone else would have had to, and it might have taken longer and been even worse. More from Marc Andreessen’s chat with John Battelle here.
