Meh. Powershell, like most things windows, is just a dumbed down version of its unix equivalent to cater to its 'lower-skilled' user base. The best thing about powershell is its documentation and help section. It's far more 'detailed' and far more examples than its unix counterpart. How many times do you just wish a man page just had an example that you tinker with to get what you want? With powershell, you get that. Another thing going for powershell on windows ecosystem is that microsoft is tying powershell with their servers to make administration simpler and easier.

But powershell certainly isn't python or perl.
