Exactly. It goes in cycles of maybe 15 years going from one extreme to the other (centralized computing <-> de-centralized).
1) single big computers and super computers
2) main frames with linked terminals
3) personal computer (PC)
4) Web2.0 / cloud and smartphones (with cloud services)
5) upcoming next de-centralized hype
