Re: Lack of integrated email/contacts/calendar?
"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."
I use them every day at work, and they purely suck. Outlook is a beast without comparison, Lync is faster than the crippleware Communicator, but has less functionality. Sharepoint, is a pain to use, that may though be our IT departments fault can't really say, still a pain and I'm missing a lot of key functionality that I do expect from it.
It's funny how consumer products are today more advanced than enterprise products.
