I saw a so-called "rival" for the OR while browsing about yesterday. I can't find the actual picture, but it's similar to the one I'll post below and was supposed to be in a price range of about $500.00.

I personally think this type of design is terrible. It reminds me of an all-in-one computer. If a webcam stops working, you're screwed until you send out the whole thing so it can get fixed.
Any design that would follow that picture I can see going wrong. Both if the ear parts give out, and also for audio quality. I'd prefer to have my own quality headset which I can switch out should something happen to them and still have the OR sitting next to me, ready to go.
I am still looking forward to this technology being further developed. Who knows, maybe one day we
will have VR MMOs not unlike Sword Art Online. You know, minus the being trapped part. Hopefully we'll have it in our lifetimes.
I really want to order a dev kit, but I'm holding back. I hope they'll have a full consumer version in the market soon.
