The first bell that rung in my ear when Steve announced Mac OS X 10.5's ship date of Spring 2007 was: "Apple just pulled a Microsoft"
It was scheduled for Fall 2006, but today at WWDC Steve announced they were delaying. It's not much compared to Vista's delay of almost four years, but why are there delays for Apple in the first place? And if there are more, does that put Apple in the same place Microsoft is in now?
I think the end of 2006 date was based on speculations/rumors. Perhaps based in fact. Here are my thoughts: to avoid "pulling a MS", the release date has a built-in cushion -- I believe the real target is sooner, but they built-in a delay cushion. If it comes out early, they rock; if not, they met their target.
True. Most opinions agree that Apple is not 'delaying' but instead using fallback dates to release sometime around Vista, either before or after.
(edit: in retrospect, this should be filed under Opinion, but is changing it now tantamount to breaching CoH?)
