Without coming across as being facetious, the camera manufacturers just love the newfound interest in photography with digital cameras. The vast majority of concerns in photo forums are with shooting in low light conditions. And folks, with their frustrations in not getting good images in low light are led to believe (via forums, etc) that getting a 'better' camera or faster lenses is going to be the ticket. So millions and millions of dollars are spent in this pursuit. Yes, one's odds will get better, but the fact is you need light, good light to readily get good images.
These images are not particularly 'noisy'. It's important to know that light falls off exponentially so with onboard flash like this it quickly becomes less-light, and that is where the perception of 'noise' comes into play.
Better technique, better lighting, and a better understanding can all help.
A 'pro' could use the same camera, or an even less expensive one and get good results.
The 'situation' of noise is across the board; a Nikon or Sony or whatever may or may not do 'better'. In fact, most P&S cameras will often yield better looking images, especially with JPGs, simply because they are overall tailored for less-experienced folks. It is often frustrating for those moving 'up' from a P&S to a DSLR when they find many images are not even as good.
