I am a manager in a 100+ corporation...My guess is that you are not. But hey, keep on babbling.
I agree with your points if the hardware was indeed only ready 2 weeks before the software. My guess based on rumors is that it was ready months before, in which case I disagree that it makes sense to wait.
I disagree. Let's put all of this in perspective. Apple caters to middle to upper class Americans. That's their market. They sell premium products. The way they have their laptops set up, you are getting a machine that serves a specific purpose, although they can all do a good number of things. If you read around on the forum, you'll see people who have more than 1 Apple product.
They'll have an Imac and an iPad, an iMac and a MacBook Pro/Air, or a MacBook pro and an Air/ipad; there are many combinations. Apple releases each product with a particular trait that makes it attractive.
The Air is small, the Pro is the full package, the iMac has an amazing screen. That's just concerning the build. With that said, people also always talk about the experience with getting Apple products.
It just works. That's what everyone says. It's easy, it's simple, it's fast, it is different. There's no denying this. Ask anyone here, that's what they'll say.
Waiting a few extra weeks to push their new OS with the most publicized and their new "staple" Laptop? That makes perfect sense. They're pushing the new MBA; hard. Why release it early when they can release it the same day and make a bigger story about it.
They can't really come out and say "hey look, refreshed airs! SNB processor, more ram, AND more hdd space!" They don't put emphasis on specs. That's not how they operate. They put emphasis on experience.
"Hey look, NEW operating system with all of these great features AND it's coming with a brand new, completely redesigned macbook air; a match made in heaven. We took the best of the ipad and macbook and combined them, AND we took the best of the iPad and computing (in terms of experienced) and combined them. "
That's generally how they are marketing Lion, if you watched the Keynote anyway.
THIS makes perfect sense.
