As a Windows Phone user this is terrible news for me because I've been syncing all my events and contacts between the services and it was handy to have one calendar that had everything on it. Also I'll not be able to link contacts and emails with Facebook profiles which was very useful in decluttering my contacts list. Does anyone have any insight into why this happened? Does it affect Android and iOS too?
