I realize this might not be the case for everyone, but for me, $600 premium is easily worth it to "jailbreak" the meta game store. Steam was here for ~25 years and I expect it to be around in another 25 years. My Quest 1, an absolute Dinosaur of the VR world now, 2019, barely works at this point, is out of support and Meta still haven't open sourced the firmware for it.
Seconding this, I love my Quest 1 but at this point it's looking more and more like it'll turn into a brick at some point. The Frame looks like the next best non-meta alternative, and a damn good one at that.
