From what I have seen PowerShell is woefully underused and unmastered by many, many folks working in the MS stack. Probably because it is so much easier to use the GUI for everything.
The MSDN site has always sucked, and it's almost always better to Google searches for MS tech help than search within MSDN or the knowledge base. (I frequently find the MSDN article I need from Google. In fact there is a MSDN search widget available for iGoogle!!!) Language and framework docs, help, and searches from within VS are quite good, and from what I've seen of VS11 beta, even better. Also SQL server docs are good.

But, yeah searching for OS docs & help is no fun.
