If you're good with 1990s era text fidelity, you'll love it. If, on the other hand, you prefer text that's readable enough to not care that it's digital, this will certainly let you down.
Even Apple's Vision Pro is only half-Retina, the same jaggedy text a my 1998 G3 PowerBook. I kid you not, the PPD is identical. And taking off Vision Pro and looking at your iPhone or MBP screen makes you want to smash Vision Pro against the wall. The displays absolutely suck -- and Frame's are even worse.
(If Apple narrowed the FOV down to about 75-80 degrees, they'd get decent text. But 80 degrees isn't deep immersion so we got 100 degrees and terrible text.)
