Many years ago, I timed the boot-to-usable-desktop time on my Macintosh II: 5 seconds. That was on a spinner, too! Although for full disclosure, I should state I had all extensions disabled. I think the normal boot time was around 15-20 seconds. I was doing packaging graphic design with Freehand at the time.I had a "gee whiz, that's fast!" experience the other day when i booted my 2010 Mac Pro 5,1 into Snow Leopard. Fast, fast, fast! And that's on a spinning drive.
