27 years ago today, Steve Jobs showed off the first Macintosh computer to the world.  This Stevenote was given in front of a live audience on January 24, 1984, two days after the famous Apple Super Bowl commercial from 1984.  Below is a video of the presentation by Steve Jobs.  The Mac has changed a lot over the years but judging by the crowd reaction, the fanaticism of Mac fanboys hasn’t.  Happy Birthday Macintosh!
