Yes, double the cost. I shopped for a portable laptop for my son for college.
Running? Unless Apple dumps the OS and all support. I have an old power PC based tower that us useless to me. Circa 2004. It is a door stop. Whereas my old Dell PC (8400) from 2004 is running like a champ. A little slow but it is still running the latest MS Office. My son used it extensively for homework last Spring. Kind of ironic that we use that PC to manage our ITunes library.
So you need to define... “running.”
“What is the market share? Where I work, we have 120 computers and not a single one is an Apple.”
Now I’m just a dumb businessman, but market share isn’t as important as:
Profit share
Profit margin
Brand loyalty
Enthusiastic receptiveness to future products.
All of which Apple has in orders of magnitude.
The rest is noise.
Best.
