Sorry, but I tend to agree with the other posters. Those pics are a horrible representation of the camera. I've taken much better night shots with the GNex, and I also have better night shots in Zurich that I took with my EVO a year or two ago. Awesome city though. The train station during Oktoberfest was very cool.
Edit - sorry, didn't mean to be so negative. I have to say that I've taken plenty bad pictures with dedicated point-and-shoots. I'm not really a photog type, but I have friends that are so I can honestly say nothing short of a nice DSLR and plenty of time playing with exposures, etc is going to get you a nice night shot. Even a very nice camera will take bad shots. Starting to ramble...that second pic is walking straight out of the train station though, right? Wow, it's very crowded. Anything in particular going on that night?
