I'm really excited about this, because it gives us another option that isn't constrained by specific platforms. I know there are complaints left and right, but we have to bear in mind it's only just been released, Microsoft is competent enough to fix the warts. Hopefully they're quickly responsive during these crucial moments of the apps release. I'm going to install Cortana and leave it on my phone even if I have to avoid using "her" for a little while. Though I hope that's not the case.
