The help system is designed to evolve over time; running `update-help` downloads the latest content. When searching for help on items, you can simply type `help commandname` to get information about a command. If you're not sure what you're looking for, but have a rough idea, you can search on partial command names, or even specify specific verbs to get a list of commands potentially of interest; e.g. `help -verb write`. The information in help gives a good overview of the commands you're looking at, along with code examples, so you can see real-world usage without resorting to the web.

Pro Splatting
When calling a method with multiple parameters, rather than passing one variable per parameter you're able to "splat" one variable to the method, with the parameters taking their values from its properties.

Commands can be chained via the pipeline, allowing output from one to be cleanly fed as input to the next.
Pro Chocolatey Package
PowerShell is installable through Chocolatey.
Pro Extensible
The language can wrap and interact with code written in other language's, making it highly extensible.

Never debug from textual traces anymore: do live debugging of saved stack traces for production errors
Cons
Con Very verbose
The commands themselves, as well as the output and error messages, are VERY verbose
Con Vendor lock-in
The environment is unique and you easily become very dependent on what it has to offer, while there is no alternative vendor to switch to.
Con The runtime environment is essentially free, but not open source.
