I changed gear this year. My feelings are two-fold. On the one hand, you almost instantly want a yet more advanced camera once you get a flavor of a leap of quality in your photos. On the other hand, you take more care of the new camera and this in practice means shooting less. If you are under the urge to hold your camera in the same way as some people use their mobile phones, portability should bring convenience for you. I was thinking of Lumix DMC-FX series. But then I see many of your photos are night scene shots, noise issue is a known problem for Panasonic. My friend has a canon ixus, I noticed this type of the camera was quite ideal for snapshots for her.
Consistency. Most of the photos if you gaze at long enough, they would not stand. What can really stand the test of time is what counts. The more I look at my own photos, the more I get impatient. I think you get better potential. Take another look at your photos some time later, see how much percentage you still want to keep.
