If it makes business sense for HP to sell workstations, e.g. their Z line why doesn't make sense for Apple? Dell also sells workstations . . . . and these aren't fast gaming computers, these are real workstations with Quadro graphics cards etc. There are many many Windows users demanding a workstation, while only a tiny few wanting a mac pro?? Apple has no desire to expand their enterprise business and only wants to stick with consumers? Even though their total profit from Mac Pro's isn't great (no where near the total profit from iPhones), the Mac Pro profit margin is healthy. Just don't understand why would a company abandon a good business. And it's not as if they have crack into the business as a newbie, it's all set up. Intel or whoever puts out new server grade/pro grade components, Apple has to re-design (maybe only slightly) the case and how it all fits, and out the door a new product. Read somewhere a writer speculated and that he hopes Apple will license out Mac OS X to HP Z workstations if Apple decides it stop making Mac Pros. He didn't elaborate, but he thought it would be a win-win for Apple and HP. How's that? Apple makes a few dollars on selling Mac OS X on a few machines, while HP would expand their workstations to include Windows, Linux, and Mac OS X.
