I’ve been following Microsoft since before they went public.
Seems they’ve passed the inflection/tipping point: still making a lot of money, and absolute figures are growing, but their grip is slipping just about everywhere. MS had to introduce their own “Surface Book” because _nobody_ was producing Windows machines right, instead cutting corners and losing sight of who their actual customers are ... while the competition systematically slices away market share. I’ve seen other big solid companies go from such unshakable dominance to “patent fire sale” in shockingly short time.
There’s a reason I didn’t go work for one big monster after I graduated from college.
