This is insane. What prevents grey market arbitrage? Why wouldn't hardware from the country where hardware is cheapest immediately get posted on the local equivalent of eBay in the country where it is most expensive?

In any case I had no idea hardware margins were so squishy. For software, yes, profits are maximized by reducing unit prices where incomes are lower (since otherwise you won't sell any), but that's enabled by the fact that the marginal cost of unit production is very nearly zero and you're still making money even if you sell it for 25% of the rich-country price. That's obviously not the case for a laptop
