Even if so, as the article notes, if you switch to some other, yet still "productive" task, you are still task switching and losing a lot of momentum on the original task. Also there will always be distractions; daydreaming if nothing else. At a previous employer my main work machine was not connected to the Internet (a nightmare for other reasons, like if I was on the Internet-enabled machine, may as well check email...). But even then, when waiting for a test that would take several minutes, I'd find myself reading a print newspaper. These forced delays kill productivity for me like nothing else. Losing the task at hand every couple of minutes to retest or really slows down output.
