Windows PowerShell

So I dl'd and tried Windows Powershell. Apparently MS tried to clone GNU bash and got a pile of fail. Have you tried it?

Discuss.

Powershell is fail. So is CYGWIN. So is bash.

I'd suggest UWIN http://www.research.att.com/sw/tools/uwin/
which is a UNIX like environment for windows. Uses the KornShell which is pretty much bash with the addition of floating point arithmetic and associative arrays. WIN.
