WHAT'S NEW IN CARDBOARD: they 86'ed YouTube!
I've sung the praises of YouTube as a virtual reality conduit, so I'm disappointed by the most notable update to the Cardboard app: "New My Videos experience, replacing YouTube experience". YouTube's VR front-end was the one app within the collection of demos that really gave me consistent utility and had the most shelf life, not being a static presentation. In this new app, Google removed the ability to use voice search for videos within YouTube's corpus, as opposed to my much smaller set of "my videos" (those videos on my device), which would be displayed in a 360-panoramic UI.

The app's effectively been rendered from a cloud-aware service to a file browser. Dang.

The previous version was really helpful, while this one is significantly less entertaining. I hope YouTube's VR version gets spun-off to a standlone product we'll eventually be able to use...or YouTube proper will responsively sniff the client being used to view the content and auto-adjust itself to the appropriate display factor - VR, 10' UI, phone, desktop or tablet.  I hope.
