The article does a good job of showing what can go wrong with Chrome, but I have a gripe with the article itself. Notice, it uses very subtle fear mongering in the way they printed the JavaScript code. At first glance, I thought it was going to be a screenshot of a Windows BSOD. I'm not sure what the author is trying to accomplish (code = evil?) but at the very least the screenshots are ugly and garish.
Pardon my ignorance, but the last time I saw DOS was around the time I was six years old. Thank you for providing some insight on this subject. DOS text editors are before my time.
