Do not mess with Engadget. The popular tech doodad site posted a email note, apparently sent from Apple servers, saying that the iPhone would be delayed 4 months and Leopard another 3. Naturally, Apple's stock tanked to the tune of a market cap of $4 billion. Apple hastily notified Engadget of the error, Engadget posted an update, and the market corrected itself, leaving Apple with a cap loss of only $1.25 billion. There's a Mastercard commercial joke in there somewhere, but I'm pretty sure the punchline is '$1.25 billion' instead of 'priceless.'
