It will be interesting to see how things evolve.

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.
