I think it will be a long time before anything replaces the mouse and keyboard. Touch is different and has advantages, by is no means "better." In fact, it is so far a lot worse for manipulating small elements such as the controls of a music DAW for example, than a mouse. Once very high quality touch interfaces come down in price, and we can afford large touch interfaces for such workstations, that's when things will start popping with touch in the professional world. That's still at least a year or two out.
I haven't figured out how to copy a link to a news article app. Anybody? This is driving me nuts!
Woody has been saying that MS might offer three distinct Windows 9 versions, including a desktop keyboard/mouse version. If so, then Windows 8 will not be helpful in preparing desktop jockeys for Windows 9. It will be helpful for Windows tablet users of course.
