Retronaut dug up this fun print ad for the first commercially successful laptop microcomputer, the 1981 Osborne 1.

From the ad copy: “The guy on the left has two file folders, a news magazine, and a sandwich. The guy on the right has the Osborne 1, a fully functional computer system in a portable package the size of a briefcase. Also in the case are the equiva;lent of 1600 typed pages. stored on floppy diskettes. The owner of the Osborne 1 is going to get more work done–and better work done with less time and with less effort.”
