Moore’s-Law-as-segmentation is not driven by manufacturing ease, though it certainly benefits from that. Rather, it’s much easier to explain to new customers.

They could introduce three new models a year (high-mid-low) and spend months advertising what they are. Or, they could introduce one new model a year, and market that.

Brand new, but low-end, customers already know the product because it’s been in the market for a year or more.
