I am waiting for something like the metaverse and I do realize that it will not happen as hoped.
I got 3D glasses in 2005 or so when I had a crt display and it was a fun novelty.
I watched 3D movies in the cinema and it's a nice novelty but I do prefer a brighter screen.
I watched 3D movie on a flat screen display and it was okay.
I got a HTC vive pro with wireless and valve index controllers and it's also a nice novelty so far.
VR is in my opinion a success if it becomes normal but no one really uses it day to day.
20 million devices? From a global company? In a market were 14 year old kids already own a 1000$ phone? Success I don't know.
People bought 3D televisions as well so that's that.
My personal expectation was that VR is going to be used for training people to drive, industriel training and lighthearted sports. But as something central like I imagined the metaverse or what ready player one proposed? We are far away from that.
That portable Linux VR headset will lay around at plenty of places of nerds having fun of it for a bit and then it becomes obsolete. An expensive toy.
