Once configured the learning curve was near non existent. It is so intuitive to scroll and swipe without a second thought that you’ll wonder how you ever lived without it. My only caveat so far is that I do think I will be digging out my old mouse pad since the back surface of the mouse really doesn’t jive well with my desks laminate surface, resulting in a very rough feel when moving the mouse around.
Other than that though it is overall a very excellent update.
