Oh, man, I have to laugh at some of these responses. It's very easy to see who the uber-geeks are, and who has spent only a handful of years in the industry.
When I started, Unix SVR4 was da bomb, and the best 3GL language out there was plain old C. Because these were the first things I used on the job, I eventually became proficient and totally biased. Now I work solely with Windows OS products and tools, but the Unix/C days taught me very many valuable lessons.
The most important -- and this was summarized at the end of the article -- was the value of using what you already have. Yes, if you have PowerShell and you know how to use it well, then by all means kick some butt. In 20 years, it will replace DOS as the old piece-of-crap brain-dead tool the noobs like to make fun of.
And, I use TextPad.
P.S. I just saw that someone mentioned Cscript, which is the correct tool name. JScript is just the language one uses.
