If your camera interface is properly designed and you've used it previously, changing to a 'night mode' setting should take a few seconds - just the same as with pretty much every other camera around, in fact.
A comparison of low-light photos on auto settings really isn't too clever if low-light settings are available.
The fact that some people don't try and change the settings on their cameras (whether smartphone or not) regardless of the conditions says more about the user than it does about the camera's ability!
My point and shoot camera gives decent quality pictures in low light when using the twilight mode with flash turned off and I prefer to use this whenever possible. Pictures of white, washed-out faces caused by a flash really aren't very attractive.
Note, I'm not denying that the Nokia's OIS is a beneficial feature in low light situations. I'm just disagreeing with the idea that nobody would ever use a camera in non-auto so low-light modes aren't worthwhile.
