I love that they are bringing something like Cortana to the desktop. Ever since I saw Her [1] I wanted something like that, something that takes away the need to look at my smartphone when I receive an email to know what's it about or who it's from. A smartwatch seems to be going in the right direction for that kind of things, but still, it's not the same as being reminded about the weather when you are on the point leaving the door instead of having to look up the weather yourself.
