Apple Computer’s Macintosh personal computer goes on sale in the United States, beginning an era. As the first mass-market PC with a GUI (graphical user interface), built-in screen, and mouse, it set a new standard for the modern computer age.
While it wasn’t adopted en-masse initially due to its high cost (compared to the Commodore 64 and the IBM clone market), it set a new standard when when Apple consolidate down to 4 models 5 years later — the Power Mac G3, the iMac, the PowerBook G3, and the iBook — with more competitive prices and aesthetic designs, Apple became profitable and started its trek to become the brand of choice for the discerning enthusiast.
Now every device, including our pocket phones, have built in screens, GUIs, and trackpads (mouse replacements). The Macintosh ushered in a computing revolution. It just took a few years longer than Apple expected.
