I do only easy things with Powershell and I found it much nicer than classical shells. It's more consistent in the command names and parameter passing. You also need to learn far fewer commands, because Powershell follows the Unix philosophy of small tools that do one thing well much more than Bash+Unix tools. For example if you do "ls" then you get a table where one of the columns is LastWriteTime. Want to sort by that column? "ls | sort lastwritetime". This works without hassle because ls returns a list of objects, and sort sorts a list of objects by a given property, instead of serializing everything to text that would need to be parsed first. I'm sure that Unixes' ls has an option built in to ls to sort by that column, but off the top of my head I have no idea what it is, and many commands that output lists of things do not have that option.

You even get autocompletion across commands: if you type "ls | sort _" where _ is the cursor, then you get a list of properties that you can sort objects returned by ls by (LastAccessTime, LastWriteTime, Extension, etc).
