I've had the Samsung S5 for almost two months now and I must point out I'm quite enjoying the overall experience on it.
The camera in particular is easy and quick to use, and when using HDR it delivers some impressive results for a smartphone. Here are a few samples:
There you go. On my recent vacation, I found I had only used my Panasonic TZ40 a few times. The bulk of my pictures were taken with the S5 and were of perfectly acceptable quality to me. Maybe this is a sign of things to come: will I actually need to get a stand alone camera next year? Convergence, convergence, convergence, convergence...
