>>>Users are required to have a Microsoft Account, formerly known as Windows Live ID, to use the Windows >>>Communications apps. This will usually be the Microsoft account that the user is signed into Windows with, >>>but if they have not done so, they will be prompted to provide one before proceeding.
Why is this a requirement?
>>>Microsoft accounts will automatically sync to Microsoft services using Exchange ActiveSync 14.0 when Mail >>>starts.
Woah there. I don't want ANYTHING to synchronize to ANY of Microsoft service EVER. This item desperately needs further clarification.
>>>If the user’s Microsoft account is not a Outlook.com or Hotmail account (for example, dave@contoso.com), >>>Mail will prompt the user to provide the password for their email account, which will be added automatically.
Again, why is this a requirement? It's not a requirement on the iPhone - ahem.
