I sort of agree, but I think underneath we still disagree. I agree that IBM didn't think the PC software was worth developing. And if they had held onto MS-DOS and approached its development in the same way that Microsoft did, sure, they'd probably be worth bazillions.
(Probably. I suppose there's market perception involved here too; maybe customers accepted software from Microsoft in numbers that they wouldn't have from IBM. But I don't know how to evaluate that, so lets pretend it's not an issue.) Where we may disagree is in your belief - what I think is your belief - that IBM was therefore short-sighted to let it go. What I was hinting at a week or so ago is that IBM was ~always~ going to judge that MS-DOS wasn't worth their bother, and they were never going to develop it as Microsoft did, and therefore (in a sense) they did the sensible thing by letting go of it, letting someone else take it and run with it. They did themselves no harm because they would never have done it themselves - and incidentally in the process they did the rest of us an enormous favor. And did themselves the same favor, because I can be certain without looking that every employee at IBM now has a powerful PC on his desk, which would not have happened had they kept control of DOS themselves. If IBM were a different company, sure, maybe that different company should have held on to MS-DOS.

The problem is that IBM has always been half-assed in the PC market. Bill Gates didn't do anything groundbreaking. MS-Windows came 6 years after Mac. The mouse & GUI was invented by Xerox before 1973. These corporations simply considered PC's chump change not worth the bother. IBM and Xerox failed because they considered PC more of a nuisance than a goldmine. > --- On Monday, August 14, 2023 at 06:56:39 AM PDT, Bob Bridges > <robhbrid...@gmail.com> wrote: > Wait, MS-DOS is what you were talking about, before?
