Loved my Mac Plus back in the 80's. (Still have it - recapped it and got it up and running recently — floppy is no go — had to boot with some kind of modern flash board.)
No internet, no passwords. When you Shut Down the Mac — click — it shut down.
Eventually, I owned a procession of more modern Macs — eventually the first install of Mac OS X. Shutting down the computer now took, curiously, a minute or so. I remember my coworker showing my wife Mac OS X and she even commented, "I don't like how long it takes to shut down." He replied, "Yeah, you'll have to find something else to like about it."
