I have no idea why people would ever think that the keyboard and mouse will be replaced by touch screens? Smart people treat touch screens news as good news because in my reality having more options is a good thing and not something to dread. I suppose the type of people who don't like touchscreens are the type that have this fantasy that touch screens will, for some inexplicable reason, render their mouse and keyboard useless, which could never happen so long as you have a working USB port, but y'know, details.
