The question it asks is Are today's Macs related to the Mac Daddy?, and it focuses mostly on the hardware. And then,

"On the software side, the primary elements left from the original Mac OS come through in the user interface," said Damer. "The single menu stripe--File, Special, etc.--is a vestige of the original limited screen real estate of the 128K Mac."

Damer said there are a few other recognizable holdovers as well. For one, the arrow-cursor remains almost identical today to its origins, and window-handling also has stayed the same. In other words, he said, today, as in 1984, you can only resize a window from the lower right corner.

So now you know. What makes a Mac a Mac is the menu bar and the fact that resizing windows is done from the lower right corner (forget about the maximize/minimize button).
