Today I had the privilege to try a prototype of the, the backpack PC that makes untethered VR possible. The PC weights around(about 7.7 pounds), but it feels quite light once it's on your back. The technical specs are a CPU Intel Core, SSD Hard Drive andGPU. It's extremely quiet, and from the vents blows a mild warm air, unnoticeable when wearing it. It runs on two removable batteries. The batteries lasts for 1.5 hours of gameplay, and they can be fully recharged in 2.5 hours. It's possible to run the PC on one battery, but the performance drop drastically.Currently the price is around, but keep in mind this is not a device aimed for home usage. It's mainly targeted for amusement parks, VR Arcades, and public demonstrations such as house and cars sales.Here some picture of me trying the device with a HTC Vive.
