P&S is 'point and shoot', meaning basic compact cameras from ultrazooms to ultra compact pocketables. As opposed to DSLRs, or 'digital single lens reflex' cameras, which are much larger, have much larger sensors, and take interchangeable lenses...these are much better in low light conditions.
However, you do have the ability to use the HHT mode with your camera to get much better results in poor light...as long as your subject isn't fast moving. As noted, no P&S camera does all that well in low light - in fact, none really do any better than the one you have, except possibly the Canon S90 and Panasonic LX3, both of which are more expensive with a lot less lens range. And even then, by engaging HHT mode, you can actually shoot at higher ISOs and in lower light with better results than ANY other compact camera. HHT is 'handheld twilight' mode - it's one of the scene modes on your dial. Use this mode whenever the light is low, you don't have a lot of movement in the shot, and the camera is trying to use a high ISO setting. Engage the mode, stand nice and steady, and gently press the shutter button...and HOLD STILL! The camera will actually take 6 photos instead of 1 - it only takes a second or two, but if you press the shutter and immediately move the camera away while it's still finishing the last shots...it won't work. The camera will need a few seconds processing time to give you the final result, but it can be significantly better than any other compact camera.
In general, just keep your expectations reasonable...it's a compact camera with a tiny sensor. You aren't going to get better low light results from any other compact camera with a tiny sensor - I promise! And avoid looking at your photos all zoomed in huge on your LCD screen - unless you intend to make 6-foot by 4-foot prints, you don't need to worry about how it looks that blown up. View it at normal screen size, or make a print and see what it looks like.
And of course, as you learn more about photography, you can start to use other low light techniques, like using a tripod and a low ISO, and letting the camera choose a long shutter speed for nice night landscapes and scenics.
Of course, if in doubt or unsure, feel free to ask around on the boards here!
