The Samsung VR headset is fucking awesome. It needs to cool down after like 10 min of viewing, which is ok with me because I like to take frequent breaks. Not only for my own eyesight and orientation etc, but the lenses become fogged every now and then. You have to try and stay really calm and breathe easily or you will fog the lenses really fast and have to take off headset to let condense.
The introduction video is a great example of what could potentially be done. All producers have to do is make 35-40 min "premium experiences" that are done in 3 segments about 8-12 min each. An interactive tour of Mars, Titan and Pluto for instance. They could also do interactive and in depth tourism based vids of different locations around the world. The possibilities are endless. Its defintely worth 100$ if you have a Samsung flagship phone.
