I think touch screens are great on smart phones. And on specialized larger screens, like for things like hotel check in. On other things, not so much. For instance; I have 2 new printers. One has a touch screen, the other has a context based keypad set that looks like a touch screen. The touch screen is a real pain to use, with mistakes common. The other one looks almost as nice but is so much easier to use.
I don't care what developers want. I'm a former developer, and when I designed a GUI it was based on what was good for the users given the technology I had to work with.
I do find it very easy to use a MOUSE. Not a mouseball, not a trackball, not a large touch screen. And I type well. So I don't need MS dictating that I change. But if they offer me a choice, with an ability to pick the best of two or more worlds of interface style, they will get my attention.
