Too bad that it doesn't seem like Microsoft applied that philosophy to most of its products (at least not back when I used their products. Maybe they've started recently -- I've stopped following them a few years ago when I bought a Mac).
I wonder if any ex-Microsoft employee ever came out and said that they actually had the explicit goal of making each successive version of their main products (windows, office) much slower than the last so that people would upgrade to a new computer, making Intel happy, and leading to more "comes with the computer" licenses instead of pirating.
