Images below are all unmodified 100% crops from their respective cameras. ISO was set on the camera but exposure and white-balance were on automatic. The Canon Powershot A700 is compared against the Konica-Minolta Dimage A2 and Fuji Finepix F10. Neither of these cameras directly compete with the Canon A700, the KM A2 is a 2 1/2 year old prosumer camera, while the Fuji F10 is a recent ultra-compact point-and-shoot.

The left column shows that the KM A2 and the Canon A700 have roughly the same amount of noise in low-light. The right column of crops show that the Fuji Finepix F10, despite being purely point-and-shoot, is significantly ahead of the curve when it comes to image noise. There are also visible differences in white-balance, with the A2 being the most accurate and the F10 being the least under low-light conditions.
Note that shutter-speeds cannot be completely controlled on the F10, so the ISO 80 to 400 shots where in Manual Night Scene mode and the ISO 800 to 1600 shots where done in Automatic Night Scene mode.
