> PMem is cheaper per bit than DRAM

Except that it's not. At best it's about the same, and certainly machines with tens of terabytes of NVRAM are in the realm of exoticware for at least a decade more. This situation is far away from the hyped state where NVRAM was going to be ubiquitous.

I have 40Gbps networking at home, and it's not even that expensive. It's not in my laptop (for some reason adapters max out at 10GBps), but I certainly can use it otherwise.
