Well, my early impressions didn't blossom into any interesting.
I purchased a great MOGA controller to give the gear VR a fighting chance, but after the novelty wore off (about 3 weeks) my Gear VR is sitting on a shelf collecting dust.
My primary complaint is that the maximum time I could keep the unit on my face was about 15 minutes before requiring a heat break, complete with a sweat clean up. Gross.
The secondary complaint is that even the best games inspire a lot of "You've got to see this" comments while immersed. Unless you buy a Gear headset for everyone in the room, most people are just left staring at some person twisting in unnatural positions. It's not a shared experience. I think the lack of sharing relegates the device to a party trick/novelty as opposed to the next big gaming paradigm.
With that said.... I will still buy an Oculus Rift for my PC to give it one final chance to win me over during this generation. Innovation requires investment, so I don't want to bail completely at this point.
