Oh ffs I get tired of this argument. Read my first comment. I used 8 for 3 months. I am slower with it. This is not me speaking of what it would be like for me, it is me speaking of what it is like for me.
I am not a touch typist. Typing the letters of programs is not faster for me.
Moving my mouse in a tiny little corner of my screen is much faster than scrolling through my programs or moving across the entire screen to get what I am after. For me, this is a fact. There is no disputing it. It just does not work as well for me. I am far more accurate and use less movement with the start menu, period.
And preference for something that works better with your working style is it's own merit. Because it doesn't work well with yours does not mean that mine lacks merit.
I am not the only one that works best this way, otherwise the outcry for the start menu would have died down by now. It hasn't. People still want it, and they want it because they work better with it.
This is not a matter of adjustment or resistance to change for me, it's a matter of inefficiency in relation to my working style. I have happily adopted every previous change to the start menu before this. Once I adjusted to it, I found it worked just as well, if not better for me, than the previous versions. But, no amount of adjustment made start screen match or better the menu for me. I don't mind alternative UIs, as long as they work well with me. I even adjusted to, and work well in OS X and like it. That just isn't the case here.
I am glad it works for you, but Win 8's UI does not work well with me (and many, many others), period.
