"Seriously, stop trying to make VR backpacks happen." Engadget doesn't have all good things to say about HP's wearable VR system. Mostly because it costs $3,500. "It's so costly, that it's even out of the realm of many early adopters. It's more suited for developers who want to explore what's possible with portable VR." Though the price is a huge issue for them, they do seem to thing it has some positive points. It's light and comfortable, powerful enough for 4K, and the best option of the VR backpacks.
