Hey if they work for you, that's great.
But the simple fact is that they don't fit everyone's brain. And that there are other tools available to accomplish precisely the same ends -- some of which have many advantages over whiteboards, in fact. Like these things known as "pen" and "paper", for example.
So this idea that they're part of "every engineer's" day-to-day work is, quite simply, disconnected from reality.
I do agree with you, however, that the problem lies not in the whiteboards themselves but in the way they've used. Which has truly been an epic fail.
