Does changing the aperture make all that much difference on small compact cameras (= small sensors)? I can't make out too much of a difference. Comments?

Which camera ?

The IXUS and quite a few of the cheaper models don't have an adjustable aperture. They only have an ND filter. Of course, the aperture does change depending on your zoom.
Don't forget what the H stands for.

Yep, a whole lot of models (most?) don't have an aperture, so there's only zoom to play with. On models that do have an aperture, the useful range is very limited and you just won't get the same effect you get on a DSLR with large sensor and lens. That's not Canon's fault, it's because the sensor is tiny and has a lens that matches it.

That said, the aperture setting on e.g. my a570is definitely does make a difference, especially in macro shooting. To get a blurry background (bokeh if you wish) from a tiny camera, you basically need to go very close to your target and focus in macro mode with full aperture.

no this is not quite true...to get the maximal bokeh from your camera you should zoom to the maximal focal distance and take your macros there. Focal distance and distance to subject affects bokeh more than aperture does on the compact cameras because their sensor is very small (sensor size affects bokeh too)
