It’s commonly said that the computer is the most revolutionary technology in the workplace since maybe the printer, maybe even ever. But those people are only half right. A computer has indeed changed the way the workplace functions, but it’s not that hulking monstrosity from the 1980s that required an entire server room to keep running. Nope, it’s that small one sitting in your pocket.

Think about it: Computers have long made communication, writing, and storing information efficient, but those jobs still could have been done, just in a longer way. Smartphones, however, made the entire process mobile. Really, for a good number of jobs these days, people don’t even have to go into work. If you have a connection, you can go anywhere.
