I posted this over in the Nikon Flickr Forum for a few friends that asked for information on the X10. I remain hugely impressed by this little camera, and have recommended it to several of my friends...not a single complaint so far. Although it will shoot Raw and also has all the other settings we are used to like P A S M, if you just leave it on EXR you will hardly ever have regrets of the result.
The Pro Low Light dial setting is simply amazing for night shots, I know of nothing better for night shooting hand held. Unless you intend large prints (above the 12MP capability) it delivers plenty adequate IQ for most needs or desires. I posted a few sample shots in the thread....

Good luck with whatever she gets!
