The iPad's Not So Revolutionary Inside
The inner workings of the iPad reveal that Apple has learned much from its iPhone development, using many of the same components and cramming those chips onto a pretty small board behind the device's 9.7-inch screen.
Context & Ripple Effects
The teardown answers the question Ars Technica posed when it dug into the A4 and A8 secrets of the iPad's brain in February: the A4 is not exotic, and neither is the rest of the board. Apple built the tablet by reusing proven iPhone components and packing them onto a compact board behind the 9.7-inch screen — the same tight-construction playbook its suppliers showed in the 2007 iPhone teardown.
That matters because the iPad launched into skepticism that it was merely an oversized iPod — the charge Slate leveled with 'iPhony' back in June 2007. The internals make the counter-case: this is a derivative design in components but a deliberate one in integration, and it shipped within a year of the A4's development rather than after a clean-sheet effort.
First-order effects
- Apple gets faster time-to-market and lower sourcing risk by buying parts it already qualifies at iPhone volumes, while the confirmed Wi-Fi connectivity issues Apple has acknowledged land on early buyers' desks alongside the new hardware.
- Component suppliers who serve both devices effectively double their Apple exposure per customer, since the same parts now ride in two shipping product lines.
Second-order effects
- Rival tablet makers can no longer differentiate on generic parts alone — competing against a vertically integrated stack (own silicon, own OS, own retail) pushes them toward either deeper integration or price competition they are poorly positioned to win.
- The reuse strategy sets up Apple's developer ecosystem as the second front: with the rumored mobile ad platform reportedly due at Thursday's iPhone developer event, the same installed base would monetize across both devices, raising the bar for any competitor that ships hardware without a comparable software business.
Third-order effects
- If component-reuse-plus-custom-silicon keeps working, the industry's center of gravity shifts toward integrated device makers who control their own chip roadmaps — and away from assemblers competing on specs.
- Teardown-driven analysis becomes a standing check on such claims: each generation's bill of materials tells the market whether 'new category' products are genuinely new engineering or repackaged platform economics, a scrutiny Apple will keep attracting as long as the reuse pattern holds.
The trend: Consumer electronics is consolidating around vertically integrated platforms where one custom-silicon and OS stack is amortized across multiple device categories, with teardowns serving as the market's audit of how much 'revolution' is really reuse.
