I dont think anyone is saying the IS is no use. I have many lens that I use IS with - no problem
I did not claim that they said, either. The claim seemed to be that lenses with large max aperture did not need IS, seemingly because the large aperture should provide "enough" light in itself. I think that is an odd view.
I commonly use my large aperture primes when light/movement conditions are difficult. Many of those are exactly when I would like to have IS for reduced camera shake and improved AF performance.
Not saying that IS is the only, most important criterion for choice of every kind of lense/usage, or that I am willing to take any kind of price/quality compromise in order to get it. But I have the 17-55 f/2.8 IS USM and the 70-200 f/4.0L IS USM, and I enjoy the IS in both of those, and I don't see any non-IS alternatives that I would rather pay for. I would appreciate IS in my 85mm f/1.8, too.
Just that IS will have no benefit for wa lens when the subject is moving and you are not panning - IS does not stop motion blur.
Hand-held wide-angles can have camera-motion-induced blurring, and if the scene is static, this can be the most significant source of blur. IS can reduce this. So can a flash, a stand, larger aperture or better high-iso performance. Since all of those solutions come with their own set of trade-offs, I see no reason to _not_ want another option if it came for free.
Of course, IS does not come for free (compare prices of 70-200 zooms with/without IS, though they are optically dissimilar). But the "please, no IS" crowd seems to be about more than price/performance arguments. It seems like a fundamentalist "true photographers can take their images without IS. If you request IS, then you should bring a stand or learn how we professionals do it". I find such an attitude snobbish, and I think that analysis of sales figures will show that they are a minority...
