Windows 8 sucks so much, it can lift matter back past the event horizon of a black hole.
My favorite Windows 8-ism, and I swear this is true, is that they removed the ability to shutdown the computer.
No, really. They did.
There's still a "shutdown" option in the new "power charm." It even brings your computer to a power-off state. It just doesn't shutdown the OS.
Instead, "shutdown" logs you out (closing all your open applications), and then hibernates the machine rather than shutting down.
The concept is that this makes booting "faster" but in my experience, it's at best a wash. (I think booting fresh is slightly faster than restoring the entirety of memory.) In any case, you still have to wait for all your applications to restart when you log in, so what's the point?! Plus, generally when I choose "shutdown," it's because I want the OS is shut all the way down for some reason. If all I wanted to do was turn the power off, I'd just hibernate the machine.
Which brings me to my next point. The Hibernate option does not exist in the "Power charm." You can't Hibernate anymore. Apparently there's a setting somewhere that can reenable this feature, but searching for "hibernate" in the new Start Menu didn't find anything useful.
Anyway, long rant short: Windows 8 managed to break the ability to turn your PC off!
