What you are seeing there is, indeed, noise: the sensor in the camera is pretty small (around 4mm x 5mm). That means each pixel site is only one tenth the area of the sites in the *ist-D, so the per-pixel noise is higher. My old Canon PowerShot G1, with a slightly larger sensor, (also a 3MP camera) produced some perfectly reasonable 8x10s of some subjects, but I don't think I'd want to go quite that high all the time. Another concern I'd have with the S5000 is the 10x zoom.
