The fact that you say MAC IS HARDER TO USE shows that you never physically used Mac, thats what everyone who never used Mac says! Or you probably did few clicks and opened some applications and did not know how to close them after
Its 2 basic difference: the mouse don't have a physical right click (you hit a key on the keyboard + a mouse click and its a right click) and 2, the maximize, minimize and close are on the left top corner, not right. Not to mention that some keyboard shortcuts are different but within the same essence. Thats it. You can also see how quickly you can switch . BTW, you will see in the videos that things are running fast, when the presenter open an application it opens in a split second, thats real (unlike a windows presentation) thats how fast things run on a Mac.
