If a PC company came out and charged premium prices but gave you the best quality PC's with a well engineered interfaces and hardware, it would do just fine.
But almost all PC vendors produce bottom of the barrel half ass crap consumer grade computers with terrible QC, that will start falling apart in a few years.
Even the big name brands like Dell and HP who could do better.... prefer shipping a crap product to reduce the bottom line.
And word gets around.
Every single dell xps I had failed via hardware after a couple years. I have Mac's that are still going after a decade.
We should be thankful that Mac exists to show us what's possible with a computer...or we would be at the mercy of these terrible computer manufacturer monopolies and thier crap consumer machines.
