Workstations have been this way since before the move to Core 2. Apple were just different for those first two and a half years. It's a niche market with plenty of spending power.
Have been what way? I'm not following. But workstations of a particular class from a particular maker are released each year (or two) with almost exactly the same price-tag yet nearly double the horsepower - at the 2 year mark. (This is generally well documented and it's even a Murphey's Law!
Or did you mean something else?
