>By the way, the famous S5 camera gives very nice photos in bright sunshine but is dreadful in dim light.
Most reviews - including dpreview.com's - suggest the S5 camera isn't too bad in low light... but that there is a knack to getting reasonable low light pictures from it.
Samsung might be communicating to its existing user-base that the S6 will not ask them to spend as long in funny menus.
An experienced human photographer will decide what 'human/aesthetic content'* in the scene is the most important to them, and make their compromise accordingly (e.g, trade subject motion blur for lower noise, or trade depth of field for a lower shutter speed). Though a camera will never know what in the scene the photographer want to capture, it can take a fair guess that most of the time a photographer wants human faces to be in focus, and for sunsets to look red and orange. These are normally called 'scene modes', and the next logical step is to have the scene mode selected automatically- Panasonic's compact cameras have an 'Intelligent Auto' mode that is usually well reviewed.
It was good to see the 'Megapixel race' peter out a few years ago, and the rise of 'premium compact' cameras - For the same reason many people choose a DSLR over a Medium Format camera (size), I prefer to carry a good compact to a DSLR. You have to choose your own compromises.
