synching of outlook
I can only stress the poor decision to remove synching of outlook from the mobile phone software directly via USB will force people to go to other software streams. Companies will not allow employees to send vital data to social networks and there fore this will severely restrict users.
Frankly, it's embarrassing to see less compatibility between 2 Microsoft products than there is between Microsoft and Apple, its direct competitor! (Because, unlike Windows Phone, iPhone supports the direct, offline synchronization of Outlook data *and* offers a cloud-based alternative for the same.)
