The Mac Pro was never going to be the biggest seller. It is a true pro machine which by definition is a much smaller market. It was never meant to compete sales-wise with the consumer laptop market which is much larger.
However it is still the flagship machine for Apple. It is their best offering in terms of pure computing power and is the only platform that is a true pro video authoring, 3D modeling workstation, scientific workstation, and software development platform.
If the Mac Pro model dies on the Apple vine, so too does high-end scientific, graphics, video, and future innovative software for the entire OS.
The Mac Pro is still an elegant beauty with plenty of muscle. The current octo runs like a beast under Leopard. People just complain too much. Frankly there is very little that can't be done with the current Mac Pro.
What is does need is more mature software, more video card offerings, and more peripheral offerings such as Blu-Ray / HD-DVD authoring devices.
Concur on multiple levels. If you want to see what a MacPro is capable of, go to the Apple "Mac at Work" website (
http://www.apple.com/macatwork/) and see how they are used by "pros".
I also agree about the capability of the current Mac Pro. I've been holding out for a refresh, not because the current system isn't capable, but because I don't want to get stuck with Aug '06 technology in Nov '07. I'd be content with upgrades to basic RAM capacity, basic storage capacity, a current video card (Nvidia 8800 or RADEON 2900), and the option for a High Def optical drive. All of the above have dropped in price significantly since introduction of the MP 429 days ago but the price hasn't budged a cent. I'm suggesting that Apple bring the current MP capability back in line with the price they are charging.
Finally, all of these are
easily doable on/about 26 Oct. They require no change to the basic hardware and, at best, a couple of new drivers.
