Or, perhaps its because that despite all the, um, outcry's of unhappiness Mac Pro sales are still strong? Since Apple doesn't share those figures we are guessing.... but I'm sure one or two Apple execs may have completed a business course or two.
Are they selling well? I guess thats the big question. I see where you're going with this- and you're right, its all about supply and demand. The price stays up as long as the demand is there. And if they can keep selling em at high margin prices, that makes the bean counters happy, and fills the needs of the market. But the question is, how do we know if the lack of updates may actually be because they're NOT selling well anymore? I don't think those MBA Apple execs would be willing to invest truckloads more money on a product that may actually be underperforming in a market niche that they have a decreased amount of interest in. When was the last time Steve Jobs gushed or even spoke about the Mac Pro? I guess we look at where the money is being spent now... iphones, ipads, and more portable, consumer-oriented macs. Thats what SJ is "insanely" excited about.
Look, all I can speak from is my personal experience, and from studios I've been involved with. Honestly, I do not know of one person who has bought a new Mac Pro in the last year or so. This studio is chock full of @60 imacs, and the last place I was at had older Mac Pros. I know a handful of mac fans that need or needed one, and the popular solution has been to either keep your original setup on life support waiting for the new model, buy a Pro on the used market like the Refurb store, or spring for a nice i7 27". Again this is my personal experience.
