On the one hand I recall a book titled “In Search of Stupidity“, which I strongly recommends reading, its about the hi-tech years that this article covers and takes a different view of how “quality” addressed market share.
On the gripping hand, I also lived though the years that book describes and can add detail. One detail is this. MS-Word was crap. Most offices/secretaries preferred WordPerfect, but MS-Word outsold WP by aggressive marketing – nothing else. The quality of MS-Word was the pits and its still full of bugs. Each release formatted historic documents in a different way, which is no-no in the legal (and other) profession. Its handling of nested indents in style sheets is a mess, so much so that many industries such as MILSPEC contractors simply don’t use style sheets.
I’m dubious about his claim that Linux has fewer add-on products.
Heinlein has a comment about democracy being like adding zeros.
If you look at those supposed products or Windows you’ll find many of them are “me-too” duplicates. We haven’t reached that stage yet with portable devices but we are getting there. When you get there, yes you do have one market leader; when people are spoilt for choice like that then a review or a friend’s recommendation can trip the balance, and that too can propagate. This has little to do with ‘quality’ and a lot to do with a cross between humans ‘herd instinct‘ and the way crystals form in a super-saturated medium.
