Edsger Dijkstra on how word processors actually make writing slower.

The irony of the situation is, however, that, as a commercial product, the word processor was so successful because, in actual fact, its usage costs time; as a result, it makes its user even more busy and feeling even better. It is the ideal tool for those that can confuse activity with work.

The experiments have been taken with people that were both experienced writers in longhand and experienced users of word processors. The outcome was, firstly, that the linguistic quality of the mechanically produced letters was not noticeably lower than that of the hand-written ones, and, secondly, that they had taken 50% more time to be written.
