The Gear VR, Samsung's virtual reality headset, is now on sale through AT&T and Samsung's US sites. The $199 headset fits around a Galaxy Note 4 smartphone, turning it into a mobile VR display. It was originally announced in September, but it's so far only been slated for a vague early December launch, though it's been available to try at a handful of malls around the country. The Gear VR was built in partnership with Oculus, and it incorporates a tracking sensor from the first Oculus Rift development kit, as well as a custom "Oculus Home" interface app. Unlike the Rift, though, it's wireless and fairly light, and if you've already got a Note 4, it's somewhat cheaper (if you don't, you'll have to add an extra $800 to the price above.) While it's more polished than the current version of the Oculus Rift, however, it's still an "Innovator Edition," so be warned that you're still essentially participating in a mass beta test of virtual reality.
