I'm wondering about the differences between Windows MultiPoint Server 2011 and Windows Server 2008 R2 but only from a MultiPoint Server 2011 perspective. For example, I don't care what Multipoint Server 2011 has that Windows Server 2008 R2 doesn't, I only care about what windows Server 2008 R2 has that MultiPoint doesn't. Is there a product feature matrix available?
think this explans it all http://www.youtube.com/user/msmultipoint#p/u/0/eT2zE5tMglM
There is a features matrix on Page 38 of the Deployment Guide.
That's about as specific as any of the MS literature on the subject gets, I think. Note that most of the features available in 2008 R2 Std appear to be available under Roles 7 Features, but a good chunk of them are untested or might be generally broken, especially running as a Domain Controller.
As for 2008 R2 Std itself, see here: http://www.microsoft.com/en-us/server-cloud/windows-server/2008-r2-features.aspx
