Multitasking gets you nowhere or does it?

Lifehacker just featured an article called “Debunking The Myth of Multitasking“.

In a fast-paced business culture of “get everything done yesterday,” it’s easy to admire and reward those busybusy people who always seem to be juggling 14 things at once. But business coach Dave Crenshaw argues that the most common kind of multitasking doesn’t boost productivity–it slows you down.

I kinda forget the reference for this, but a while ago I read that, with each interruption, the brain will need about 15 minutes to get all things in order again. This so that you’re at the same situation that you were when you were interrupted.
