Their dedication to developing a true VR computer and focusing on specs that really matter for that (PPD and raw processing grunt) are commendable, but seeing them champion the idea of strapping an X86 computer to your face in what is an increasingly arm-powered world is... concerning. "But it can run real Adobe Acrobat through WINE" is not something that gets me excited about a VR platform, but I'm likely not the target audience either.
That being said, having tried out some remote-desktop apps on a Quest 2 earlier this year, the screens are absolutely not acceptable for that purpose in terms of viewable resolution -- so if the Quest Pro really is only slightly better in that regard, I think it'll soil the experience.
If Simula can manage to tune their x86 specs to run well enough under power-limited circumstances, have at least comparable poor battery life to other VR headsets, develop a VR computing environment with usage paradigms that make sense, and do it in a headset that's somehow still comfortable to wear for extended sessions, then they may truly be ahead of the curve in a way that matters. That seems like a big ask for such a small company's first outing, but they also seem the most passionate about this category of use-case despite their scale.
I wish them the best. VR computers like the one they're working on would be a lot cooler than Meta's vision for the category.
