I read the article where Brian Tucker (Intrinsic) said his customers are going to wait until SP1 of ConfigMgr 2007 is released before moving to the new version of SMS.
I have to say from watching the community, through the forums and the email list threads, there are more than quite a few companies rolling this thing out right now. Granted some folks still have it in the lab, but with the intent of moving to production pretty quickly. And, the really cool thing is that, possibly, 30% of these are folks who have never used SMS before or have in the past but chosen something else until now.
That means Microsoft has done a great job with this SMS update. It also means you don’t need to wait until a service pack is released before giving it a try.
Go ahead, you know you want to:
