You've probably already watched all the videos embedded in our posts "The 10 Best Ads to Come out of Steve Jobs' Reign at Apple" and "10 Songs Steve Jobs Made Famous," which were a part of our our admittedly hyper-nostalgic reaction to the news of Jobs' resignation on Wednesday as Apple's CEO. Well, to close out the week, here's one more: A grainy video, just over five minutes long, of a young Steve Jobs introducing the Macintosh on January 24, 1984. Jobs was just 28 years old then, and he hadn't yet settled on his future trademark uniform of black turtleneck and jeans, but he was already every bit the showman. This particular version of the video has been on YouTube since 2006; I've seen it before and maybe you have too, but it's been making the rounds again this week (I spotted it at least half a dozen times in my Twitter stream) and I have to say that watching it again -- on my MacBook -- once again gave me goosebumps.
FYI: The credits at the close of the video read "Recorded in January 1984 and preserved for the world by Scott Knaster" -- now a technical writer at Google -- and "Restored and digitized in January 2005 by TextLab."
