Last week, I ordered a $US 12.00 Google Cardboard as they were $5 bucks off in the Canadian Google Store. I don't mind being two years late to the 'Virtual Reality' party.
I discovered that my Nexus 5 would no longer be supported with new Android updates and so I needed something to play with. (I am pretty sure that I will soon be able to download a build of Nougat for the device, because that's what poor nerds like to do to keep an unsupported Android device up-to-date.) Anyway, the glasses, made literally of cardboard, have kept me occupied for a few hours already. I had to clean my phone so as to not magnify the smudges from my greasy fingers. The Nexus fits perfectly in the end of Cardboard, of course. Now, I can fill up my phone with VR apps until I get sick of playing with it.
I didn't expect much, but I can see why people have continued to forecast that VR will the next big thing. Now, if I can rid of this headache ...
