Answer to the Dock Question.

Arthur (Operating System)

The answer to the poll is Arthur (operating system).  Arthur was initially released in 1987.  The thing is at that time they did not call the docks but icon tray.  Arthur was the first of its kind to bundle this program with the operating system.  Windows 1.0 and Linux did not have anything like an icon tray until much later.  The icon tray from their evolved into today’s dock, which as of right now the Mac OS has and also Stardock have made their own dock.  Linux also has a dock program that can be installed from third party.  But only the Mac OS come with the dock packaged with the OS.
