I just installed it. So far.....eh. To use Cortana you must establish a Windows ID. It didn't like it so I created a new one. It asked for the password twice in order to get rid of it, in order to log in with a pin number instead. Took it the first time, not the 2nd. Not sure if it's a bug or not. Gonna wait a couple days and see if there's an update. Anyone else install it today? I think today was the release date.
