I suppose that I am somewhat of a mix between a cmd line and a GUI kind of person. I like and use both. GUI has definitely opened up computer use to the general public. Most have no time nor desire to get deeper than that and for too many that is still too confusing. As long as they keep upgrading I am sure M$ and friends are happy but with tablets and smartphones in the forefront of marketing the desktops and notebooks are starting to ride in the backseat.
