I think the biggest problem is that the FOV is tiny on these things, its good for a while, but I'd much rather use a giant screen than use googles where my head gets sweaty and takes a while to set up.
I actually don't want an ecosystem or an oculus account or a vr storefront, I just want a monitor for my face. If I can't have that without the nonsense, I guess I'll just wait until they go bankrupt and sell all the patent IP.
It might be that we get to a point where it's more open, but I hoped the same for a bunch of other products (lytro comes to mind) that never made it.
It's not like I don't have steam installed on every computer I own, but it's more of an on principal thing. I don't buy razer mice because I don't want to spend $50-100 on hardware that doesn't work properly if the vendors download servers go down, and razer mice have very strange profile defaults if they can't talk to the razer desktop program. If razer goes under it won't really be possible to move razer mice to new computers after a while.
Similarly, I'm really not keen to buy $800 worth of kit that could become a paperweight if I get VAC-banned. I'm a big fan of separation of concerns on this front. I might part with $100 with a dependency on steam because that's throw-away money, but not $400 and certainly not $800.
The main issue I see is relatively low resolution - with normal monitors you have at least 1920x1080 covering small percentage of your view; with VR there's half of that covering whole view. Increasing FOV without providing better resolution will only make it worse.
This can be especially noticeable in games with large distances (like ETS2) and games with small text size. For those I'd definitely like to see a headset with at least 4k resolution.
