The spec sheet FOV may not be the absolute largest available, but it doesn't seem that compromised. FOV is tricky to measure and just looking at numbers to compare two headsets may not give the whole picture (pun intended). The custom fit and prescription optics allowing the lenses to be at the optimal position for your eyes without needing glasses may make the FOV better in practice than other headsets with a larger theoretical peak FOV which isn't achieved due to imperfect fit.
Norm from Tested[1] and Brad Lynch[2] are two of the most knowledgeable and experienced VR reviewers out there and they've both used it and did not report that FOV was noticeably worse than Quest. The clarity of the optics, the resolution, and the contrast ratio will be much better and could easily make up for a couple of degrees of FOV.
I'm surprised I haven't seen people talking about using this as a monitor replacement for laptops or desktops. People talked about it for Quest Pro but this has significantly more pixels per degree and is much more portable (for 3DOF use at least) and comfortable, which could address the biggest issues with Quest Pro for that use case. I would definitely buy this over Quest Pro if I was interested in monitor replacement.
