People who used computers before the Mac recall they were all about text -- green, light blue, or amber dot-matrix-style letters on a black background. Building on work at Xerox PARC, Apple changed that, bringing us a screen in which everything was a graphic, including text. The Mac came with MacPaint to make that fact that crystal-clear. (You can still use the original Mac OS via James Friends' emulation website.)
Today, GUIs (graphical user interfaces) are the norm, whether in Windows, Linux, Android, iOS -- even ATMs, car stereos, and kiosks. Folder icons, trashcan icons, and the desktop concept came from the Mac. What we see and do on a computer is much more like the real world than before the Mac.
