Agreed. I would go further and say that MS had to do something to get in the touch screen game, but their idea that you can or need to have a keyboard / trackpad driven device (laptop or desktop computer) include touchscreen input is just adding a feature that doesn't really work.
You can't easily, or naturally, move your hands from the flat horizontal plane in front of you, when typing and using a touch pad, to the vertical plane of the screen, as it forces you to stop doing what you're doing in one plane, to shift to another. And once you do move to the vertical plane, you have to use significantly more muscle and motor skills to hold your arm / hand / fingers in place long enough to do what you could / should have been able to do on the keyboard / trackpad.
Anyone who thinks this isn't true is either fooling themselves or has some bizarrely long fingers that do not require the hand to be lifted from the keyboard to touch the screen in a meaningful way.

My Sony Ultrabook had touch screen and I never used it. In fact, it caused me problems because if my hand accidentally brushed the screen it would launch an app or close a window, hated it.
