Some photos taken with a Canon EOS M but I'm not going to do a review, there are others that can do it better than me: review[en] or details[pt].
What I can say is just my opinion: very light to carry around with us, very easy to use, quick on focusing, great control of the ISO, high quality of the LCD and images. Overall very versatile, is not difficult not to like this camera and quickly get used to. An advantage over the DSLR is that you hardly miss a photo because of this easy point and shoot instead of missing something because you took to much time looking through the viewfinder, for example, analysing the best way to take the shot. Is good for using on vacations or for the ones that like to do photography daily but in a discreet way and without carry much weight.
