When Apple first launch Macintosh, it starts with the 1984 commercial, which mimic the George Orwell's novel, 1984. In George Orwell's 1984, the people are controlled by the 'Big-Brother'. George Orwell has another novel named Animal Farm, which sounds more interesting to me.
In the 1984 commercial, the ads says, "why 1984 wouldn't be like 1984". At that time, the PC industry was lead by IBM personal computer.
Apple Macintosh is a big leap for personal computer, it features using of mouse pointer and graphic user interface on a 128k ram computer!
Mac OS System 1
Mac OS X 10.9 Mavericks
There is an engineer, Jeff Keacher use his 27 years old Macintosh plus to connect to the Internet. It is very slow, it takes a few minutes to load a html page, but it still "works". You can read how he do it here.
The Mac hardware and software are so much different from the original Mac. Some of the look-and-feel of Mac OS has not been changed, for example the menu bar of the application is always on top of the desktop not on the application windows (as in Microsoft Windows system).
What I can say is classic remains there!
Happy Birthday Mac!
