How do Windows 8 and WP8 work together?

Currently I'm an android user and considering upgrading to a Windows Phone. I have Windows 8 and have to say I'm a fan of it. One thing I'm really curious is about is how WP8 interfaces with Windows 8, aside from the obvious stuff like moving files back and forth (which is easy to do on Android as well) or Skydrive integration. Anyone? I hear this in a lot of reviews but I don't know specifically what it means outside of some syncing...
