The Keyboard Tax and Why You'll Pay It Anyway

The MacBook Pro's five-year evolution presents a textbook lesson in how markets function when consumers have no choice but to accept what they're given, which, on reflection, is how markets always function.

Consider the design changes. Apple has removed ports, thinned the chassis, and altered keyboard mechanisms — each iteration reducing material costs and manufacturing complexity. One might say Apple is optimizing for profit margins. But that's unfair. Apple is optimizing for *consumer utility*, which coincidentally manifests as reduced functionality per dollar. These are not contradictory. The firm is simply discovering, through revealed preference, that customers will pay premium prices for devices that do less but weigh less. This suggests that lightness itself is what consumers demand at the margin, not capability.

On the other hand, the performance improvements are indisputable. Newer chips deliver legitimate speed gains. This creates a genuine sunk-cost dilemma for existing owners. Your three-year-old machine is now a depreciating asset that has crossed an invisible threshold of obsolescence. You've already paid $2,000 for hardware whose resale value is $300. You might as well upgrade — the incremental loss is already sunk. This isn't wasteful behavior; it's rational actors responding to circumstances.

But I must reverse myself. The real issue is *lock-in*. Workflows developed on Apple's ecosystem create coordination equilibria that professionals cannot defect from without incurring switching costs exceeding the price difference with competitors. Users aren't freely choosing the MacBook; they're rationally imprisoned by past decisions. This looks like demand, but it's really path dependence wearing market clothing.

Unless — and I must note this — software availability is itself genuine demand. If the ecosystem offers tools Windows doesn't, then preferring the MacBook is agents rationally allocating capital toward functional tools. Apple isn't imprisoning anyone; it's solving coordination problems everyone agreed to stay inside.

To be clear: the MacBook Pro's five-year evolution reflects pure market forces. Whether that's good depends on whether you were going to buy one anyway, in which case it was inevitable, or whether you're reconsidering, in which case you won't, because *you will*. The performance gains justify nothing; the design changes justify everything; and your next purchase was decided the moment your current machine started feeling slow at the margins.

The only question the market actually answers is how much you're willing to pay to avoid admitting you're locked in.
