30th anniversary of the PC and the post-PC era [Editor´s Note]

Where has the time gone? It is the 30th anniversary of the IBM PC. Many of us might remember when IBM announced the PC (formally the Model 5150) on August 12, 1981. There were many computers at the time, but predominantly mainframes and minicomputers. Computers were largely seen as costly resources to be time-shared by large groups. The idea of a "personal" computer owned and used by one person was a relatively new notion for most people.
