Indeed I dislike Win8 also. The GUI alone is reason enough.
Shutdown has meant the same thing since donkey days, and then MS starts messing with it.
Again: what MS calls a shutdown, by default the fast shutdown/restart, is in fact not an actual shutdown. Therein lies the problem.
If I tell someone to shut down the machine I expect the thing to be off. Not in some semi-hibernation state.
But it is good to know the difference and advise accordingly.
