Besides the features are values indicating the likelihood for the feature to be true. All of these are educated guesses and none have been commented or confirmed by Apple themselves.
As the saying goes, “bad news sells newspapers”.
Being true to this saying the traditional media (CNN, New York Times, etc.) are again reporting the Mac rumors as fact. Even with a recent example of how irresponsible these traditional media were; CNN iReport incident.
You can see from Dow Jones Newswires article Apple Sets Oct 14 Event: “Spotlight On Notebooks” they are referring to all the rumors about what Apple may announce as facts. They even went as far as suggesting that Apple is using this event on October 14, 2008, 09:30 (PST) as a tactic to recover the falling price of Apple’s stock (AAPL).
This Dow Jones Newswires’ Ben Charny has such high regards for Apple, that he is basically suggesting that Apple has such a great foresight, as to predict the collapse of the US economy and the global financial market. So they planned approximately 2 years ahead of time to have an event on exactly October 14, 2008; several days after Apple’s stock price broke its 52-weeks low a few times, to make announcements that will recover the price of their stock. That is utterly ridiculous.
