Add that you've got a lithium battery pack pressed against the back of your head -- those things don't have a perfect safety record. If it blows up in your laptop, you probably won't be permanently disabled. Or that excessive use of the device will probably have long-term consequences for your eyes. As a long-time user of smartphones, I am beginning to wonder if staring at a small screen has accelerated aging in my eyes. I can only imagine the damage from poorly calibrated VR glasses.
