content: I've watched over a hundred hours of movies and tv inside a vr headset, so I'll weigh in. For TV viewing, up to 45 minutes I'd say, there is basically no fatigue or comfort issue. I've done that sitting up, laying on my back, and on my side. 20-45 minutes is very doable. Movies can become problematic, atleast with the headsets I've owned. The substantial reduction in weight on their production hardware might be enough to solve it, can't say yet. However I've watched 90 minute movies with just the occasional adjustment between sit/lounge/lay to stay comfortable- its not ideal, but not too bad. Sweating has never once been an issue for me, except when I've used the headset to jerk off to VR porn- your average sweatiness may differ. Outside of the comfort, the viewing experience is amazing. 3d, which I hate in theater and on tvs, is un-fucking-believably good. Its everything I thought 3d would be before I was let down by all other experiences. The motion and quality is amazing due to the low-latency OLED displays used. If the slightly low resolution and bit of black crush are fixed, then it would hands-down beat any display I've used. I'm honestly super excited for the next generation of slightly lighter, higher-res vr headsets. I strongly suggest giving one a try before bashing em too hard.
