The idea behind PSVR is to bring VR to the masses. We already have VR running on phones (I'm purposefully leaving behind how they perform, btw), so having it on a dedicated platform is a no-brainer.
While I still need to test it for myself (the only approach I've gotten with VR has been with Samsung's Gear VR) I think Sony's idea is right in the money. I just hope they decide in the future to allow its use on PC...
