Nice set of first images and I like the abstract feel to these images.
Unfortuntaely, you will always read negative posts from people about any camera - quite a few are also posted by people who have "Tried" but not purchased and slate the camera.
Camera purchase for me is a personal thing and I tend to wait following release and then read user reviews from genuine owners rather than the armchair critics that are ever more abundant on forums these days.
I purchased my X100 last Dec after doing my research, looking at images from users and going into shops to handle / try the camera, once satisfied I took the plunge and purchased and have not been dissapointed it does what it says on the box and offers me a small / light / tactile / retro style camera with incredible IQ that exceeds my recently departed
Leica M8.2.
I find the AF is ok for my street work and the occasional times when it struggles to focus are no different than those I have experienced with other cameras so on that note, let me congratulate you on your purchase, welcome you to the fold and wish you many years of happy shooting with a superb small well built high quality camera and do not be too influenced by what others say, it is your camera so use it as you see fit.
Some of mine below - 4000ISO better than anything my Leica could have done!
