Have to agree. Although not touted as a major feature of SP2, it certainly improved the processor thread handling such that Vista SP2 performs almost as well as Win 7 RC.
It's a fundamental improvement that I'm sure MS won't want to trumpet as:
a) It shows that there was something fundamentally flawed with Vista until now and
b) It removes a reason for wanting to pay to upgrade to Windows 7 (although there are many others that still make it very worthwhile!).
