A lot of functionality is the same between the two. You long click to get a context menu, or right click to get it immediately (if that's enabled on your Apple Mouse, or you use a PC mouse with a Mac). You click and drag to reorganize it. Applications minimize into the Doc Icon if they're docked, and are added to the right of Docked applications (not Locations, like Downloads or Trash) if they aren't (when they're launched/opened).

The Dock on OS X handles Docked Folders considerably better than the Taskbar on Windows. It isn't even a comparison.

Both implement "Jump Lists" and "Recently Used" for Apps that support that.

The biggest difference between The Dock and Taskbar is Aesthetics, where the Dock Wins, IMO. Simply because it's just a Dock, while the Taskbar does too much.

The System Wide Menu Bar on the Mac prevents issues like Win32 Apps looking like junk because the color shifts from Toolbar to Menu Bar is often drastic in these applications. Again, this is largely an aesthetic difference.

The fact that it takes up room at the top of the screen doesn't matter, because in applications that use a Win32 Menu Bar or Ribbon, the same amount of room is taken up in the Application Menu. It does tend to allow applications to look more aesthetically pleasing to segregate it out of the window, and some functionality benefits come from that, like the Full Text Search within the Help Menu of Mac Applications.

The Apple Menu doesn't serve the complete identical purpose as the "Windows" Menu in Windows.

I greatly prefer the Stay Position on the Mac, and the fact that icons don't disappear or appear based on "what's used most" or "what was used most recently," or whatever Microsoft does (by default, it's configurable to a decent-enough extent). The biggest thing I hate is the Action Center Button being on the bottom-right of the screen, and the fact that Notifications pop-up in that corner of the screen. Just doesn't make sense to me.

You can move the System Tray to the top of the screen, but that will take the entire Taskbar with it :-( You cannot separate the two.

I do prefer the Cortana Icon on the bottom left of the screen (on the Taskbar) in Windows ( I really hate the Cortana "Search Box" as it's just too damn wide), compared to the Spotlight icon in the top right on OS X. I think it's more efficient to have a function like that in a more accessible, plainly obvious, spot on the screen.

Also, I had to read "but I don't know why you do is all" about 10x before I actually got it. What area of the country are you from (generally speaking)?
