I think it is a conceptional proof that xpoint (read: Crosspoint) is coming. Today, sure, there is little use for it, once the motherboards have adjusted and the true potential, as lanes and micro connectivity has been adopted by the industry, we will hopefully see this option more as a hybrid nand or supporting it in some way or fashion. Today it is still more like a bridge in between the old and the new. It is only like 7 years in de making, it has only been "known" outside of the patent offices and in the open for the past two, maybe three years. What this device is for is for OEMs to give it a shot, to see how it runs in their hardware and for us enthusiasts to start thinking about the history of a hard disk in a computer. I am looking forward to the first devices that use this devilish fast storage, could even be a phone, or maybe it is already inside the new 2018 iPhone.... who knows!!
