Back in the day, there were three things you could do with a Mac mouse. You could click, you could double click, and you could drag by holding down the mouse as you moved it.
Now, there are sixteen different "gestures" you can make with a Mac trackpad (including "force click").
How can something so seemingly simple, actually be so complex. It is elegant in its way, and I may eventually learn to like it. But, there is definitely a learning curve.
