Bascially this. Since the return of Jobs, Apple has not been first about anything (and one may argue about them not being so back in the day as well). But Jobs always had a flare for marketing.
Can you have loyal customers with just marketing? Certainly you can get them to buy a product, but marketing doesn't create satisfied customers post purchase. Being first is similar. You can certainly get some nice industry buzz (marketing) by being first. People will buy the product, but will they be satisfied? Only if it is well designed.
I feel like the Blue Origin / SpaceX "first to land" is relevant here.
Blue Origin (another Bezos company) was technically first to land a rocket, and gloated about it. But SpaceX has a more useful implementation as of now.
