We like virtual reality headsets, but we also refuse to accept any such headsets with displays below 7-inches in size. Thankfully, the Oculus Rift VR headset met those exact specifications in its latest prototype update, going from a 5.6-inch LCD to a 7-inch 1280 x 800 display. Sadly, while we got to get a much closer look at the updated development prototype, we didn't get to actually use it -- Oculus reps told us that, while the hardware's working, it's not quite ready for press prime-time just yet. But that doesn't mean Oculus had nothing to show -- not only have a variety of hardware tweaks been made (a new, custom sensor, for instance), but the software's been optimized. Oh, and there were some new demos to show off, albeit on an aging prototype model.
