There are currently two competing implementations of virtual reality available in the market. One makes use of a powerful but relatively immobile computer, be it a PC, laptop, or even gaming console. The other uses a smartphone to trade power for portability. ASUS already has the latter, with the just announced ZenFone AR. According to leaked internal documents, however, the manufacturer is also eying the former. ASUS is reportedly working on a standalone VR headset, but its "AIO" name leaves the door open to something slightly different.
