Currently I'm using a local account to log into Windows 8. Back when I was setting up my Windows Phone for the first time I used my existing WL ID and it imported all my MSN Messenger contacts (which I found rather irritating as the set of my MSN contacts is pretty much disjoint from the set of people I call on the phone). I ended up resetting it and setting up again.
So now I'm wondering whether I should use the same Live ID I have on my phone for Windows 8 or create a new one to avoid unexpected consequences regarding data that is already associated.
Side question would probably be: What exactly is associated with my Windows Live ID already and would be used or altered by Windows 8? My guess would be at least
- Calendar data
