These things look pretty cool and all but I just can't see it taking off for mass market consumption.
Most people I know don't even use the 3D function of their 3D tellies because you have to wear "stupid glasses", hell I've never even bothered trying the option on my projector. Mainly I can't see many folks wanting to strap a massive thing to their head and lug around a pound of battery.
As a niche product for porn, theme parks, science or the DIY helper thing it could work nicely but as for mass market I just can't see anyone wanting it.
