Anyway I thought that my Sony DSC-V1 takes decent night shots, but then I compared them to my friends DSLR 
While I did manage to make some semi-decent low-light photos with Sony DSC-F828 (e.g. this (1/3s without tripod), this, this or this), I certainly miss higher ISO settings and lower noise of a DSLR. Actually, hardly any of low-light photos (or any other, for that matter) used F828's highest ISO800 setting - the noise was unacceptable (despite 'noise substraction' function). Of course, if you want to use infrared 'night shot' feature (e.g. here), the 'grain' is unavoidable.
However, my biggest complaint is not low-light usability, but handling of high contrast, that is, the blasted 'purple fringing' (which is distinct from rather tolerable chromatic abberation); see street lights here or sky visible through platform roof girders here.
