Most of you probably are already aware of this little development, but there is a freeware IDE for PowerShell development (Scott beat me to the post...). It really is great. One of the most interesting parts about it, at least at first glance, is that it gives a first look at what an IDE might look like if it were to use Office 2007's ribbon. Not only that, but it even has an Mac OS X styled (or ObjectDock if you're so inclined) tool section in the bottom right.

Sweet!
