I have been following the developments in virtual reality, and I love the direction where it is going. The technology, to be honest, is still young and to mount different sensors to use HTC Vibe, can be a deal breaker if you do not have a dedicated area.
I also think it is too expensive as it is, and it needs to be tethered to a different device.
Microsoft is also touting their solution mixed reality which is a combination of Augmented Reality (AR) and Virtual reality (VR) which base on reviews is less complicated to set up, requires less computer power than the two VR headsets mentioned in your post.
Even cell phones are now offering VR. Daydream by Google and also Samsung with their own VR headset.
I believe you will still get an epic experience although the technology behind virtual reality is fairly young.
