Apple has maintained a level of secrecy surrounding its tablet project not seen since the iPhone about three years ago, John Gruber says. Referencing sources at Apple, the historically accurate technology writer reiterates that a Get Smart-like "cone of silence" exists surrounding those developing the tablet and virtually no information comes from those directly involved. Many of those involved are the same who developed apps like Calendar, Mail and Safari for the iPhone and underwent a similar routine in late 2006.
