This is barely related but there was an article published recently about abandoned virtual college campuses in Second Life, and this reminds me of that.

I imagine the possibilities for visualisation and telepresence in education through VR is great, but I wonder how costly it would be to implement and to provide the hardware to students.

I plan to use it to watch pornography, OP.

Right but you can already access free educational stuff with just the computer and internet. This while scenario seems a bit off to me. Who is this family too poor to send a child to school (which is free, so we're talking maybe uniform, book and travel costs) but can afford a computer, good speed internet and a VR headset? How is the professor doing a real time talk enhanced at all by VR? What is happening there that cannot happen with a stream or video-conference?

I want to see Nirvana in concert or the Doors in VR also going to virtual movie theater or a 90's arcade. I can't wait for VR this past few years of gaming has been a disappointment when it comes to pushing tech hopefully Virtual Reality will be the kick in the ass this industry needs generation HD remake is getting old.
