Visual Studio 9 Code Name Orcas Installation day

Installed Microsoft Visual Studio 9, code name Orcas today. I just wanted to get a feel for it because I will be writing the new Bandwidth Vista using .NET 3.5 and wanted to know what new functions are available. So I haven't done much with it yet. Some of the new C# language features look cool, the 'var' type which is interesting. The downloads where massive all compressed into a rar file which took around 30 minutes to unzip, even on my newly built Pentium D 3GHZ - wow! So it should have a lot of new features I hope....
