Anyone who's interested in VR but doesn't want the high outlay or to commit to particular hardware just yet, and has any half-decent Android or iOS phone, should check out VRidge from RiftCat. It turns your phone into a Steam-compatible VR headset; just get one of those head-mounted phone holders and away you go.

VR controls can be an issue; the software lets you fake them with a standard game controller, but I haven't found any easy way to have full VR controls (real first-party VR controllers all seem to be tied to the headset, and third-party software that uses things like Wii remotes and Sony PS Move controllers seems complicated and fiddly). But for this EmuVR I don't think that VR controls are likely to be a sticking point.

EDIT: The VRidge site says that it supports iOS as well.
