Apple's (AAPL) iPhone Duo sells out minutes after pre-orders open, according to Apple Insider

Launch-day sellouts of this kind are a recurring feature of Apple's flagship release cycle and have historically been a weak demand signal in isolation, since initial production runs are deliberately tight and pre-order stock is rationed by geography and model. The distinction that has mattered in past cycles is what sells out: premium configurations with higher storage tiers selling through first tends to read as positive for average selling price, while broad sellouts across base models have often reflected constrained supply rather than extraordinary demand. Lead times on Apple's own store, rather than the sellout itself, have been the more informative metric the sell-side tracks in the weeks after launch. The follow-ons of note are channel checks on build plans and supplier orders, any shift in shipping estimates, and how carrier and third-party inventory behaves once initial allocations are replenished. As a single headline it carries little weight on its own; the pattern that has historically moved the stock is whether early demand signals are corroborated at the first quarterly print covering the launch window.
