I think the issue with it is, that it is not so much the addition which will necessarily wow you (beyond the first minutes), but rather the removal, when you go back to 110° which then will seem awful. I understand this kind of sentiment that people may think that you’ll forget about the additional FOV after some minutes and no longer notice it, appreciate it. So that means it’s not worth the effort, the additional GPU load, etc. because you don’t really appreciate it, right ? It may seem like that when you are using the awide FoV headset and get annoyed with some flaws it has which your previous narrow-FoV device didn’t muster; but only when you actually do go back you will see that you can’t go down that route anymore.
VR is a world of compromise and will remain such for another while. To some this compromise may seem to be too costly - they’d have tro try it for a couple of days to see how going back makes them feel about their alternative.
And if you were into more active, wireless room scale VR I guess the Vive Pro with its wireless module simply may be checking more boxes with you that the Pimax would do today.
