Your post does unfortunately add the general confusion about Microsofts progress with CRM2011.

You do not mention af word about Microsoft Dynamics 2011 On premise.

When will cross browser support be available for all your On Premise customers?

From my point of wiev, you would support us all by forgetting all abour integrating Yammer.

Wery few uses that.

Spend the time creating real cross browser support running, including support for iPad and Android clients!
