This is my first experience with VR technology and I find it fascinating. The potential seems unlimited. Here are some general observations:
1. My biggest disappointment is probably the overall graphic clarity of this unit. Where's my HD? When you consider the quality display available using the Samsung model 8 device (approaching 4K resolution), so many of the VR presentations available are, frankly, less than someone might experience watching a standard definition television. Donkey Kong lives on!
2. As with so many things in life, you get what you pay for, really applies to VR headsets that are marketed in that $150 dollar price point area. Optics are so important and I suspect the lack of optical quality seen in the Gear VR unit is a large reason resolution suffers. I would have gladly paid another $100 bucks to get an upgraded glass on these headsets.
3. I do not like the presented menu designs when using the set. Don't get me wrong, the background graphic and the 3D menu suspension is awesome. It's the overall organization of the menu content that needs redesign.
4. The controller has problems. Sometimes you can't even get it to appear on the screen without having to place your arm is some awkward position.
Well that's my two cents, for what its worth!
