The PC's greatest nemesis was born 40 years ago today

The Apple Macintosh is 40 years old today. Far from the first home computer, the Macintosh has become one of the most well-known. Announced back in January of 1984, the Macintosh became famous as a personal computer that could compete with the IBM-compatible PCs that were so prevalent at the time. Or perhaps it was the George Orwell 1984 inspired Super Bowl ad that drew in the crowds—Apple sure does know how to make its products appear desirable.

That wasn't going to cut it if Apple was going to compete with the IBM PC, introduced in 1981, which would begin a wave of IBM-compatible PCs powered by Microsoft software.

Enter, the Macintosh. Developed alongside the Lisa, the Macintosh was a whole lot cheaper than the Lisa despite using the same Motorola processor. A whole lot less RAM helped reduce costs. It launched for a cool $2,495 and included its own GUI alongside two apps designed to show off all the Macintosh had to offer: MacPaint and MacWrite.

The Macintosh was a ready to go box, including a 512 x 342 monochrome display and mouse, and that really helped sell it en masse.

Steve Jobs would talk up the Macintosh in his famous style, too, which would later become even more popular with the invention of the iPhone. The line? IBM is the bad guy, big blue, big brother and Apple is the only one that can
