The birth of Apple Lisa has an interesting story behind it. When Steve Jobs and his colleagues were taking a stroll through Xerox PARC, a research and development center, all of a sudden they were subjected to see an advanced machine called the Alto which utilized a bitmapped graphical interface and a pointing device called a mouse. This sight inspired Jobs and his party to develop a unique platform, exclusively for Apple and thus gave birth to one of the first two commercial micro computer systems equipped with a graphical user interface. But the high price and frustrating slow speed resulted in the death of Apple Lisa.
