The pendulum swings
to and fro... When I had my first computer course, there was a big HP 3000 in some part of the building, and we had 'terminals'. Along comes the PC, breaking up the big mainframe into smaller modules. We've gone from big honkin' iron in the closet, to mini silicon under the desk to big honkin' iron in the cloud, which could be another room in the building. It's not that hard of a concept.... the great material continuum. What was once old is new and vice versa.
