Good stuff, but it still seems to reflect an assumption that is all too common in such surveys. Your article doesn't put it that way, but the linked study says, "The results also showed excessive time is spent reading and writing emails, with approximately 65% spending from 1 to 3 hours per day doing each." Who decided that 1-3 hours/day is excessive? The often-implied assumption is that ALL time spent on e-mail is wasted. The rest of the report focuses, as it should, on how much of that time was wasted and what we can do about it.
