A couple years ago, Yahoo! estimated that 2% of the users visiting their US properties had Javascript disabled (the percentages were generally lower for their non-US properties). I would guess the percentages are even lower now. If you're concerned, you could estimate it for your own site. Let's say that by having a site that degrades gracefully without JS you can increase your user base by up to 2% -- in that case, you have to estimate whether the extra revenue from that 2% exceeds the extra development, maintenance, and support costs. For a site with a relatively small user base, probably not worth the effort, but as the user base grows very large, it may start to be worth it (of course by that time, the no-JS population may be even smaller).
