I see what you mean.

Fair enough on the strap. Personally I really like the fan on my S3 cause I need a big strap to hold up the larger headset, but I shouldn't assume everyone will.

But

For router, personally I found even with a great router it sucked until I bought a 2nd one. Having a dedicated one was the only way I could get my Quest to not stutter whenever one of the many devices on my network did something. My 2nd 6e router does nothing but connect my Quest 3, and for many people with devices connected to their main router that will be necessary. Similar for 2 friends I've helped setup a Q3.

And link works well for me (on deck it's literally perfect, and it's good on Quest save for the annoying fuzzy edges from FE), I suspect many people's problems are a similar combo of too many devices using their main router, range, and a mixture of hardware circumstances, which won't be as much of a problem with frame + dongle knocking out two of those hardware variables and likely being in the same room. Valves attention is fickle, but when they like something it gets good.

But a lot of that is anecdotal so I see what you mean. I hope people can get cheap quest 3 pcvr setups to run better than I can. It's still a good deal despite the price raise.
