And what is the point then? I'm serious since i read this "if you do not understand why then it isn't for you" but without any explanations about what isn't understood.

Think about other products that exist in the wild. Have you ever looked at something on a shelf, or in someone's hand, come to an understanding of what it is and what it does and then thought, "That's stupid. I don't need that. There are better options!" The thing is the person using it loves it , and it's solving a very specific problem for them, a problem you don't have.

It's the same thing here: you don't respect the product so you don't understand who would use it, so you don't buy it. That's fair enough.

But the MacPro is designed for a niche audience who are happy with the hardware, implementation, support, and so on. The things they're doing with this product are not things you're doing, so you don't understand their pain points.

This doesn't answer the question though. The question was "why would you buy this over a pc with the same specs?" and you answered essentially with "if you do not already know this then you cannot know this".

How would one gain that knowledge in the first place? We aren't born with the knowledge of why one would buy this machine over another.

We gain that knowledge based on specifics of the two machines. So the question is simple: what specifically makes the new Mac Pro a more desirable purchase option for someone than a PC with similar specifications?
