I've been programming and using computers for (too many) hours a day since I was 12 (11 years ago). When Windows 8 came out, I literally spent like 10 minutes looking for the shut down command. I guess it wasn't intuitive that you had to mouse down to the bottom right corner of the screen, click the icon usually reserved for "settings" and then click shut down?? Maybe I had an early release candidate or something weird, but I decided to give OS X a try at that point...
Yeah, you're not supposed to shut computers down anymore. You close the lid and it goes into hibernate. Or for a desktop, you walk away and it eventually goes into hibernate by itself. It's part of the commoditization of computing. You don't need to know how it works, you just use it to do what you want and it does everything else behind the scenes.
