the problem is not just when you wrap it, is that if you move the cable in any way (say, move your laptop around, trip on the cable, etc), it will bend in that spot. If you tie up your cable in the loop-up-then-down-then-sidewise it will improve things, but then you will put it in your bag and it will bend at that spot anyway as soon as some pressure is applied on the up-loop. This is why every manufacturer uses strain relief, including apple now. Saying "users are using the product the wrong way!" is the epitome of form over function.
