That gives a a delivery date, five days later, on *Tuesday* 24th February. Apple also signalled new iMacs are imminent two weeks ago and in particular that existing reseller orders for 24" iMacs may not be honoured:
I suspect that this indicates that the 24" production line has been switched to producing an entirely new model, probably the expected quad-core with a new cooling arrangement, while a version of the 20" iMac will continue much as it is now.
The most recent developer release of Snow Leopard appeared to approaching final as it asked developers to concentrate of third party application compatibility.
Then there was the Apple director's slide showing a first quarter release of Snow Leopard:
Given that releasing a paid-for OS revision shortly after shipping flagship Mac models either involves bad-publicity or an expensive 'up-to-date program', or both, we can understand why Apple may well have delayed the shipping the new 17" MacBook Pro, and chosen to coincide the release of the new iMacs with Snow Leopard which is expected to lever significant speed bumps over the previous generation iMacs.
My money is on an Apple event announced on Tuesday 17th February to be held Tuesday 24th to launch Snow Leopard and the new iMacs. There could be an advance announcement for i7 Mac Pros and a 'one more thing' NetBook which will be much happier running the slim-line Snow Leopard than the current 10.5.x. Expect Apple Cinema TVs and new iPhone/Touch's in the Summer. I expect this to be an exciting year for Apple, and me.
