Another reason there aren't enough iPads

This may come as a shock to some Apple bulls, but Cupertino is indeed subjected to the same laws of physics as we mere mortals are. In fairness, I'm a major Apple bull myself, but the Mac maker is susceptible to supply shortages like any other company on Earth, even though it already has the best supply chain in the world.

Just five days after it was unveiled, Apple had already sold out of its new iPad allotment for preorders. Domestic shipping times have now slipped to as much as two to three weeks for new orders placed directly through Apple, so clearly there's a bit of a shortage relative to demand.
