People with VR problems come here for help, but we don't hear from people who aren't having problems. It's probably similar to the 'tip of the iceberg' phenomenon - you don't see or notice the majority of it because its hidden.
I'd wager for most people, once their VR problem is resolved, it is no longer an issue.
Having said that, it's still new, it's got more demanding hardware requirements, so it's not surprising when problems arise. I went the TrackIR route on my way to VR as well - and still prefer it when flying bombers because of the necessary keyboard use when calibrating the bomb site.
One thing that makes me sad is the idea of someone aging out of the game without ever having tried VR. It's THAT much of a unique experience. We are so close now - it's no longer unaffordable, and Hitech's implementation is one of the best out there. It's difficult to describe - you just have to experience it yourself. It's in a completely different class from hat switch views or TrackIR, because you are INSIDE the cockpit. It feels like you are INSIDE the game itself, not just interacting with it on a panel in front of you.
