I suspect the 2013 Mac Pro was sort of an experiment by Apple to test out the market for high end desktops. The radical redesign reflects where they think desktops are heading or at least where they see the market for Apple desktops heading. I think each design choice makes sense if you look at it from that perspective. - Limited internal expansion / high speed external bus : In a future world where every computer has USB-C and/or ThunderBolt ports external expansion is going to be the obvious choice for most people. Very few individuals/companies use desktops exclusively so interoperability between laptops & desktops is another factor here. This is also true of internal storage. Fast internal storage + NAS/SAN are clearly the right direction to go here. - Less CPU / more GPU : You can scale many highly parallel / CPU intensive tasks in the cloud or on a rack of your own servers better than you can buying the latest and greatest Mac Pro every few years. GPU processing is harder to scale outside of the box sitting on your desk. This doesn't meet everyone's needs today but we're talking about the future here. In 5-10 years are people going to be replacing their desktops often for more processing power? Some but probably not enough to make a high end desktop Mac a sustainable product for Apple. - High base price : This is the real test. Anyone can say they want a high end Mac desktop but how many people are actually going to buy a $3k+ desktop? How often will they replace it? The price probably reflects the minimum amount of profitability Apple wants to continue making Mac Pros. Now it has sat on the shelf for 3 years. Are people still buying it? Like it or not that's a factor Apple has to consider. Can they sell old stock or do they have to update this thing every 6 months for it to be a viable product? So if this was indeed an experiment we can only speculate about the results. Either the Mac Pro (in it's current form) is not a viable product for Apple or they're going back to the drawing board based on their experience with the 2013 model.
