I disagree, this can also happen when a internet user decides he doesn't want javascript enabled on his browser because too many people have abused it. Or if a user just doesn't have it enabled because he doesn't know any better. When designing websites I feel that you need to expect that the user wont be able to figure out if he has javascript enabled or not. Again I use javascript , its not bad but... there are cons to it. You have no control of settings people choose on their browser.
