Interesting. Now that you've made me think about it, I've realized that I use Windows more like a single-threaded operating system. I only ever flip between applications (ignoring my second monitor). I never, ever, combine multiple applications on the same monitor - this is crazy because this was the Windows 95 promise. Not that it's a bad thing, I'm used to the workflow and love it.

I absolutely agree with your guess as to why this is.
