I was writing a PowerShell Script for the 2008 Window Scripting Games (are you in the games?) and I found writing a long complex script using only a text edit to be really tiring.
I blogged about a PowerShell IDE two years ago, but for whatever reason it didn't stick. I didn't start using it regularly and fell back to the command-line and notepad.
However, while I was writing scripts for the Games I got fed up with just the command-line. I went back to http://www.powershell.com and starting coding in the PowerShellPlus Editor. You can get it free. Schweet.
This IDE has come so far and it's a joy to use. It's got a debugger and intellisense and syntax highlighting. It's like SQL Analyzer, but for PowerShell. It's a great way to not only learn PowerShell but it's very powerful for advanced users. Seriously, go get it.
