Less effort. Key-strokes + click on 8/8.1, as opposed to opening the Control Panel, finding the most likely group for the thing you forgot the name of, and then clicking on the thing you need. The control panel is bloated, and it's organisation is not entirely logical (to me, at any rate).
Effort reduction is a fair point. However, most of the shortcuts presented are for tasks I do so rarely that having a quick shortcut to them adds relatively little value.
The few that I do use frequently from that list already have their own key bindings, or I can find them with 2-3 keystrokes after pulling up the windows start menu (something you can't do with Windows 8 if they aren't regular applications; you have to type and then select a different application category to search in).
Ctrl-Shift-Escape == Task manager
Win-D == Desktop
Win-R == Run
Alt-F4 (from Desktop) == Shutdown
The net result is that this is not enough of a value add to elevate Windows 8 above Windows 7.
