Until I had my hands on Playstation VR I couldn't understand the need for any VR that wasn't mobile. Samsung Gear VR and Google Cardboard are both "good enough" experiences with price tags a mere fraction of those of hulking VR systems like HTC Vive and Oculus Rift. For most people the only VR you need is the kind you show off at parties and family gatherings, and never think about again.
