Clash of the mouse and finger cultures
Putting the taskbar at the bottom of Metro apps vividly demonstrates the new clash of cultures introduced by the Win 8.1 Update. It’s really hard to tell where the touch-centric universe stops and the mouse-centric world takes over.
To see what I mean, press Windows Key + Tab to pull out the list of running Metro apps on the left side, then hover your mouse at the bottom of the screen. You get two lists, from the two different Windows worlds.
It could be worse. If you have Metro snapped apps running side-by-side, the taskbar only appears once, stretching across the entire screen. Thank the Windows gods.
