I used Panasonic Lumix LX3 last season, took over 1,500 pics, and was
quite happy about its quality and the ease of use.

In addition to meeting all criteria you mentioned, it also:
- shoots HD video at 720p
- has wide angle lens (24mm equiv)
- has capability to attach a filter or wide angle conversion lens (I
used one to make it 18mm)
- can shoot in raw mode if you want to pursue the quality of picture
- its fast (F2.0) lens makes it a good snapshot camera too when
drinking beer after landing
