Because touch is the future

We are on the very beginning of a new computer generation. Windows 7 is the pinnacle of the mouse age, but that age is ending.
I think you've made some big assumptions there, and we have yet to see if they pan out.
Touch is the present, for mobile devices.
It works well in that area...
Touch has been tried and tried and tried for the desktop environment and has yet to succeed.
It doesn't mean that it won't, but I wouldn't say for sure that it is the future.
It might be.
Gesture might be..
Voice might be..
Some combination of those...
And a keyboard and pointing device of some kind might also be..
I'm not convinced that touch will work with the desktop.
Then again, I'm not convinced the desktop will survive other than in business and some niche areas...
