As we walked out of today's Google I/O keynote, we -- and all other keynote attendees -- were handed the second-generation version of Cardboard, Google's low-tech effort at a VR headset. As was announced at the keynote itself, the new Cardboard is designed to fit phones that are 6-inches or larger, which makes sense given the size of Google's own Nexus 6. It's also now much easier to set up; in just three easy steps. Another improvement is that it no longer has the magnetic ring trigger of the original, which apparently didn't work with all phones. Now it has a simple top button that when pressed, activates a lever coated in capacitive tape -- think of it as a cardboard finger touching the phone's screen. This, of course, makes the Cardboard viewer compatible with a lot more phones -- including, yes, the iPhone. http://www.engadget.com/2015/05/28/g...hone-hands-on/
