Apple can't do anything about the underlying technological reality that there's a big difference between current consumer desktop platforms and current workstation/server platforms. They're also being hurt by the fact that the base configuration Mac Pro is quite different from the typical configuration Mac Pro. For consumer PCs, it's common for the base model to be one of the most popular configurations, but for the Mac Pro the base model is a niche product that relatively few customers will opt for. This defies the expectations of people who approach the Mac Pro as if it is a consumer product.
