The proportion of potential users priced out of owning a Mac vs. a PC is much lower than Ferrari vs. Kia
What I mean to say is - customer base for Mac vs. PC overlap alot and aren’t distinct as you seem to be alluding to.
From anecdotal experience one big reason was always:
‘You can get the same specs in a Windows PC for 1/2 the price !!’
Now with M1 - you can’t get comparable specs/performance in a Windows PC.
Also - in the past few months I’ve seen M1 MacBook Airs at very competitive price points. There are actually cases where you get better performance at a lower price point compared to a Windows PC.
I do think the M1 / ARM pivot has been a game changer. Market share in the last 12 months seems to be on the up.
That was never really the argument. Even in the heyday of the PowerMac, you could get one for $2000 and it was competitive with a $2000 PC. But $500 PCs existed and were 75% as fast, whereas $500 PowerMacs did not. And then that's what everybody bought because for most people, the last 25% of the performance isn't worth four times the money.
It's the same reason $50 Android phones have higher sales volumes than $1000 iPhones. For sure the iPhone is faster, but is it $950 faster? For most people the answer is no.
