I've talked about this before. I owned a touch screen laptop long before Win8 came around. I constantly find myself dismissing dialogs with the touch screen rather than using the keyboard, trackpad or even the mouse (I use a mouse with my laptop frequently). It's easier, more intuitive and with the exception of using the keyboard, faster. I also scroll fairly frequently using the touch screen as well. On the desktop things will be *slightly* different, as the monitor is a bit further away. However, I *have* wanted to purchase a touch screen monitor because I love the touch screen on my laptop so much.
That's pretty much what I said is stupid here. No one is going to "join them" because they whine and moan so much. If anything, this behavior will have the opposite result.
