I wish people used the term HMD (head mounted display) for stuff like this. It’s not VR, there is no motion tracker or interaction with a “reality” that is “virtual”. It’s just really small screens really close to your eyes.

This really seems like a solution in search of a problem.

I don’t think it’s a bad idea in principle, but what got me suspicious is that I couldn’t find the resolution anywhere on their page. From the only picture of the screen I found, it looks painfully low res:

For me the huge advantage of this is being able to read without holding something. I often like to read lying on the beach for example, and hate having to hold my Kindle over my head, this would potentially solve that. Not really worth $350, but still, I like the concept.
