Windows 7 is final and includes .NET 3.5sp1
Very happy to see that we announced that Windows 7 is done! My wife has had this on her laptop for a month or so, and is very happy with it. My media center is running well at home with it. My work laptop likes it too.
For those of you WPF developers out there...it is exciting to see .NET 3.5sp1 ship as part of Windows 7!

To answer the question in comments "won't it include .net 4.0?":
Nope.
Windows 7 is done as of July 2009. .NET 4 shipped Beta1 in May 2009, and was not trying to catch the Windows 7 train. It is not done yet.
