You want to know what i as a professional care for? Money. That is it. The difference between a Professional and Wannabe-Professional is quite simple. The later spends money on stuff he doesn't need or overpays on stuff he needs. I don't want to overpay and i will not overpay. It is as simple as that.
"How is it embarrassing? Professionals care about performance. Others may care more about superficial things like specs and recency. Maybe you can answer the question I asked above and have asked repeatedly of critics of the Mac Pro, what professional task is the Mac Pro unable to efficiently accomplish?"
There is nothing superficial about specs and recency. In fact a professional who doesn't care about performance won't need a Mac Pro. The customers of the Mac Pro are the ones who care specs. You apply the arguments that are reasonable for th average user on professional users. Yes the Mac Pro surely will do every Job most professionals need to do. But here is the catch. Why would i pay double the Price! And yes it is double the Price for a Mac Pro. There is absolutly no justification for that. Hell even the superior Support won't make up for it. I would rather buy a better performing machine two times or three times. And that's that. Wasting money doesn't make you a professional. Professionals care about money the most.
You see the MacBook Pro comes at a price that is reasonable. Similar products cost the same or are slighlty cheaper. But the Apple design and support make up for it. But not for the iMac and also not for the Mac Pro. It is as simple as that. I have no idea why you are trying to defend a product that clearly has outlived its product-life-cyle. If you are a customer and are defending apple's current ripp-off on the Mac Pro...well then any further discussion is meaningless.
But since you so care so much about what i do. My job changes every few months. I am an engineer and actually i don't have one area. Sometimes i only work with Excel, Powerpoint and Outlook. But at times i build simulations with AnyLogic or PlantSim. At other times i run Forming-Simulations etc. The list is long and the requirements differ greatly. But i need and want a Desktop-PC that is reasonable priced and meets my Standards.
I will summarize now:
I am content with the MacBook Pro currently but would love to see 32GB.
I am not content with the Mac Pro and won't buy it.
I am waiting for an iMac update and will see if it reasonably priced.
I have made up my mind. Thanks by the way.
