DIMM outlook on that
Putting a NIC interface on a large capacity piece of storage should be a much larger seller than putting the storage in the memory of one's PC. Having the NIC storage (NICmem) would allow one to have their storage for their PC, their Tablet, & their phone in one location & pretty much available all the time.
Eliminating all the hardware between the internet and the data should save considerable amount of hardware (read energy) costs as well. Maybe Google will then be able to move their memory a few more blocks away from the Bonneville dam to a lower rent district.
This will be true until the first case occurs where someone or some institution has their data pilfered by a government and used against them. Then the addition of DIMM to the memory space of a PC will brighten somewhat.
