Nothing really holds you to switch to MS Outlook. You will have Outlook, calendar, address book that is linked to LinkedIn, Skype, Facebook, Twitter. You can easily upload pictures and any documents into OneDrive. You also will have Xbox games. Plus you can use Reading List application to create bookmarks and access them from any Windows devices. Music service is available too. The list is going to be very long to continue... In my opinion, the Windows Phone is being hardly accepted at consumer level simply because of bad marketing and lack of device selection. Go to any mobile store here in Canada and you will hardly find any Windows Phone devices. Ask any sale person what services are available from Windows Phone platform - they do not know. Ask advice what to buy - the answer is Apple or Android. Plus ask your IT for BYOD - most corporations does not support WP.
