During Covid lockdown I worked remotely and used my VR headset exclusively. It took some getting used to but I much preferred that over a laptop or even a multi-monitor desktop setup.
Probably the same reason why people continue to use Facebook and its products...they don't care about privacy and they like being abused and fed lies from every avenue possible.
Not everything has to be about privacy or Meta. The Quest isn’t a productivity platform and it’s most likely going to be a terrible experience if you were trying to use this as a PC replacement. There’s literally nothing else you can do natively on it. And even these "apps", they’re just a browser window. It doesn’t work offline. You can’t have a notes app next to it. I don’t see this going anywhere at all.
