> 3,500 seems SO worth it if this can be used to comfortably replace external displays

Agreed, but that's a huge IF. The ergonomics problems with VR headsets are well documented - has Apple really managed to transcend them? I'm not gambling $3500 for a thing that probably ends up sitting in a drawer because it gives me neck cramps or eye strain or motion sickness.

If Apple wants to drive adoption they need to lower that risk. A way to have a trial period or a one-week rental would help.
