Supposedly some at&t stores will be getting them today. For those who don't know, gear vr is oculus and samsung's first vr consumer product. It works with a samsung note 4 android phone to create a 3dof 1440p vr headset that runs proprietary oculus vr software.
This particular version is the innovator edition. Consider it more like a public beta. These things will update on a 6 month cycle – next will be the galaxy s6 phone in 6 months, then the note 5 in 12 months, then the galaxy s7 in 18 months and so forth.
Launching today is vr cinema, a personal movie theater app, and hero quest, a vr Zelda clone.
