Those are valid points, especially your point about fidelity, current tech is good enough for gaming and apparently not good enough for work (or we haven't figured out how to use it right). So they can sell it for that right now.

But this and other comments are vastly underestimating the resources that people would be willing to exchange to make their work better. For what I described, a "reasonable" price point could easily be around $10,000. Apple is selling their new iMac at a starting price of $5,000 and there is nothing particularly revolutionary about it, it's an upgrade of what is already available. When you are spending all day using it, and it is the tool you use to make your money, it is worth a lot.
