I agree that you have to start somewhere for miniaturisation, but if this technology is introduced prematurely and consumers don't take to it, you may be doing more damage than if you just let the tech mature in labs and commercial applications. Just look at the Virtual Boy. VR tech died at the consumer level when that failed.

I doubt that you could get hours of gameplay. Maybe if you were playing something very simple, you could do hours, but a fully immersive world would destroy battery life.

I thought a quarter was pretty small (in UK here, so not sure of the comparison). In my opinion, this company is bringing what is currently a multi-thousand dollar setup down to consumer price levels. If they don't get the response they expect from this campaign, who is going to invest the millions to make it smaller? Surely that WILL be the death of these type of systems?

As for power usage, graphically intense 3d games on the iPhone 5 have about 2-3 hours battery life on a 1.5Ah battery (thats screen, CPU, GPU, etc), so I'd say its still perfectly realistic to expect hours. I don't know the power usage of this kit though, but i would expect it to be low solely based on its function.
