I'm facing a flight from Scotland to Australia in December where I'm going to be sat in economy class on a no-frills Air-China flight for god-only-knows how long, and my options to distract myself are currently either read a book on my kindle, or play or watch something on the iPad. I would kill for one of these.
The problems with my existing options are that I can be distracted by seeing people moving around next to me, or I can check my watch absent mindedly, or one of many things might happen that could bring me back into the reality of being sandwiched into a sweaty tin can. Time can pass very slowly when you're travelling.
VR on the other hand completely transports your mind to a place where time isn't really relevant anymore. You need to block out all of your surroundings to really make it work, which means no seeing other passengers get up for toilet breaks, no listening to the engine buzzing along as you read. If I could put this headset on with a decent pair of headphones, and all of a sudden be flying around space in some mobile equivalent of Elite:Dangerous or watching a movie in properly immersive 3D then time would just speed by and my flight wouldn't be so bloody awful.
I've got an Oculus DK2, but I sadly can't lug my beast of a desktop PC on to a flight with me to power it. In terms of being the VR headset of choice for gamers, I'm pretty convinced that Sony will eventually win that battle with their PS4 Project Morpheus headset. This won't compete with either of those two excellent experiences, but I think that as a traveling accessory at least, a wireless headset that uses your phone as a screen could be a god-send.
