Based on the marketing material it seems that the Quest Pro is targeted at enterprises where a $1500 device which helps improve employee productivity isn't that big a deal.
Spending $1500 per employee for a fancy gadget might not be a big deal for Facebook and Microsoft, but they are in for a shock if they expect the rest of the corporate world to cough up the cash.
Not every employee at a company gets the most powerful computer, nor does everyone get the expensive software. This is targeted at companies and employees who can benefit from the tech such as architects.
Even Facebook / Microsoft don't give out VR headsets to all employees.
This is also a first gen product, so this is not the version most companies may be adopting.
