The only place I find camera quality to be bad is in low light, but it's not the hardware, it's the software. The camera software just sets the ISO higher than it should and overexposes everything in low light. I use FV-5 to manually set a lower ISO and manually set the metering point so that it doesn't overexpose the shot, and then I can get great shots in low light. If you don't know a little about cameras or aren't willing to take the time to manually adjust low light shots though, you'll be disappointed. In decent lighting I can get some great shots even with the stock camera app though, especially with HDR.
