Yeah...I guess you are right.

That's an excellent point.

The VHS vs. Betamax argument may apply here.

I suspect that, at the end of the day, this is the real reason for the
success of the PC. It's easy, as an engineer, to second-guess it and ask
why it couldn't have been "more" than it was, but I suspect a business
person would look at me funny. From a business perspective, it was wildly
successful (until the clone market undercut IBM so much they got out of the
PC business altogether). In economics vs technology, economics almost
always wins.
