The Magic of Doing One Thing at a Time - Tony Schwartz - Harvard Business Review
Multi-tasking vs Priority-listing. I suppose it does depend on your goals and personality. I found this article appealing despite my preference of having the TV or radio as background noise while flitting from computer to computer (I see little reason in sitting and staring down the screen while a program updates or downloads or whatever - it should wait for me, not the other way around). On the other hand, there is some sense to the idea of getting that most important task done (taxes anyone) on time when required.
