Not everyone wants a camera dangling from their neck like some kind of optical necklace for all the holiday, for one its uncomfortable, it can get annoying bobbing about and it potentially targets you for theft. I used to carry my apsc camera in a rucksack when on holiday and tobe honest after a while getting it out and putting it away got tobe a chore it got to a point that i didnt take it out in the first place.
All this is academic really only the op knows what compromises hes prepared to accept in terms of size, weight and image quality. For my needs the rx100 is the perfect size and offers great image quality for the price is it perfect...... no its not then again no camera is.
