Let's share stories of our first Macintosh experiences! I'll go first.
It's been a few years now, but I seem to recall that I first sat down at a Mac in a department store in shopping mall in Wichita KS around 1985 or 1986. They had a single Mac on a desk just off the furniture sales area. Nobody was even there to sell it so I sat down and started drawing things with MacPaint. I'm not sure I had even heard of the Mac until then so it was quite mesmerizing. Later, I would get MousePaint for my Apple //e to try to recreate that experience, but it wasn't the same. It's amazing how rudimentary MacPaint is by today's standards, but back then, it was revolutionary!
