I first sat down at a Macintosh in 1986. Prior to that, I'd worked on early PCs and Commodore machines. The Mac blew me away. It still does.
Here's a pic of the first Mac I could actually afford. I've owned several since the venerable Mac Classic, but this one holds a special place in my heart because it's the first one that actually lived with me and became part of my personal space. The way my other Macs do. And the iPod. And iPhone. And iPad. And AppleTV.
