Luke from Linus Tech Tips indicated that 3dof "VR" might be damaging VR as a whole, as it gives people an unrealistically awful impression of what VR has to offer. This is in contrast to what I originally thought of Cardboard+co: low barrier of entry teasers. After repeatedly hearing that VR isn't special from people who have only used these low-end devices I've been forced to agree with Luke.

These platforms should drop the VR moniker - they are 360 stereoscopic ten day wonders and little more.
