Today, January 24, is the 21 birthday of Apple’s Macintosh computer. It is hard to believe that the Mac has been around that long. An article on Mac OS X Rumors this morning also talks about the Mac’s birthday, and links a movie file that shows Steve Jobs announcing the Mac for the first time. Two things struck me about this video: 1. How revolutionary the Mac was at the time it was released. 2. How enthusiastic a bunch of geeks can be when you show them a cool new “toy”. Check out the video here.
