One of the lucky few, Redditor user "jonomf" shared his experiences after the fact. The headset apparently produces absolutely no tracking lag and a very high frame rate. The unit's two screens combine for a resolution of 2,160 x 1,280 and the only disorientation jonomf reported was upon taking the headset off. Interestingly, he described the transition from the Valve headset back to reality as feeling fuzzy and distant, almost as if reality itself was a downgrade from the VR experience.
As the unit is still a prototype, we aren't sure if it will retain its interestingly long face, especially since the bottom half of the screens are seemingly out of view. Valve has also been working up some creative ways to use their new, better than reality itself, headset. For instance, when you're not actually up for gaming yourself, you will be able to take part in a "life-size Dota 2 VR experience" where you're a spectator watching heroes dole out destruction upon one another. There was also mention of a lag-free hardware solution that will help you turn any room in your house into a Valve-powered holodeck. Now that's a reality we could really get used to.
