Two days later, Apple founder Steve Jobs presented the Apple Macintosh 128K with Bob Dylan's song line "The Times They Are A-Changin'". The device was named after the apple variety "Macintosh", "128K" stands for the available RAM. What was truly revolutionary, however, was the square box next to the computer, called the "mouse", and what was displayed on the monitor: a graphical user interface instead of flashing command lines, on which the displayed elements could be operated intuitively. Apple did not invent either of these things. But the company from Cupertino, California, made these technologies suitable for mass use for the first time in 1984. Fittingly, the computer itself announced in a robotic voice: "Hello, my name is Macintosh. I'm not used to speaking in front of a lot of people, but I'd like to tell you what I thought when I first encountered an IBM mainframe: don't trust a computer you can't lift."
