Paul, your comment: "I agree with the previous comment, wait until a later version has been released and see for yourself"
I think we need to be dabbling a bit now. At the moment, most of the design of M2 has not been tested under real conditions. I mean it is emergent from 1.9, but it is a huge leap in some areas. I'm not sure all the decisions about separating out settings, navigation, clustering of functionality etc really will work under real conditions. Some thngs will need to be changed. I'd like to see a few server set up and used for a few classes even if there are some bugs.
