The thing that excites me about VR is the potential to experience historic building and museums through VR instead of having to travel to the location.
VR is the new human-computer interaction that interesting and intriguing. Instead of going to places physically, I can just sit here and the world comes to me.
I love the idea of the endless potential that VR could have. To think that with all the advancement in smartphones, that a device you carry with you can "plug" right in and get you going sounds awesome! Every VR experience would be customized to you since it is running your phone on your profile. Just amazing when you think of the possibilities.
Combining VR with smartphones is a great idea because it can give new life even to slightly older phones (just use them for co-op VR games or something).
