Re: Lack of integrated email/contacts/calendar?
Love the translation from Bing:
"As the City Council in 2004 , decided to blow off the computer software giant Microsoft "
As to "But if you're not tied to MS ecosystem already, why would you willingly adopt it?"
I can only assume that you have never used Outlook / Lync / Unified Messaging - together with Office / Sharepoint / Yammer, etc? It's awesome. There is no comparison to any other product - it's the best integrated suite and the most powerful and pleasant to use product in that space that there is by a long long way.
