It's hard to believe that I wrote this more than three years ago:

What I find especially frustrating, though, is how Microsoft forces me to spend so much time pampering their software. Yes, I'm talking about Internet Explorer, the iconoclastic web browser that refuses to acknowledge web standards.

How much online productivity is lost trying to get websites to look and function properly on Internet Explorer?

That would be an interesting question to explore. Talk to just about any web designer, and they will tell you that, for every 100 hours they spend on design, 50-60 hours are dedicated to actual design, and the rest is devoted to creating xhtml and CSS hacks to get it to work on Internet Explorer.

This is just as true today.
