1. Google Glass: This is the most underwhelming and lamest thing ever. Tried for 20 seconds and never thought about it again.
2. 3DTV: meh, I’dr rather watch 2D.
3. Magic Leap / HoloLens: this is way less cool than the commercials, tiny field of view, incredibly far way from something actually usable.
4. Oculus DK2: jaw dropped, holy shit moments. WOW!
That’s not to say VR is perfect. In fact, it’s far enough away from perfect I currently never use it. But it is so much more impressive and close to being amazing than these other categories.
