We used to run print production for a major advertising agency mailing millions of pieces per week using 8gb of ram with Dual Core G5s. This machine is aimed at designers/agencies with fat budgets that might need to do Video editing / light 3D work / After Effects every now and then. That was always the bread and butter of the previous Mac Pros, it's also why they tried to make it look nice on your desktop (though I think they failed) Honestly, Apple is not worried about the segment of the market that needs 192GB of ram - I'm sure it's orders of magnitude smaller then the ones who need 64GB.
