Well, focussing on the high-end market with unspectacular products at a spectacular price point has worked so well for HTC in the mobile phone market.
actually holding it together...
I do buy the "Pro" thing though. I'm looking at the defining feature of the device as being just one single thing: The quick fit and release procedure afforded between the 90 degree hinges, the ratchetting mechanism, and the headphones which seem to have the sense to actually stay folded out, when put in that position (EDIT: ...and the padding, and all that). Only that: A procedure that makes passing the device expediently between a succession of users easy; Much like the design of saftey bars in a rollercoaster, or that huge lever at the back of the old Virtuality Visette. :7
This is what makes the device targetted to the commercial Vive customer base that HTC has fostered, and not so much home users, although they'll certainly not turn down anyone's money.
There is apparently currently no enterprise plan available for the Pro, but it's probably just a matter of time until that not only comes, but existing contracts can be upgraded with new "pro" units.
I'd go so far as to say that, with the above, I'm pretty convinced HTC would absolutely have tried to get away without updated screens if they could. As it is, they did at least have enough awareness to realise they and their product designation would have been properly laughed at, so they had to increase the resolution, and not just to 1440p which would have brough PPD parity with the Rift, but surpassing it.
