I'm thinking for size and shape,one of the Casio Z cameras.
I had a Z-120 and it was awesome pocket camera with a great zoom and did video pretty well.Some of the other cameras mentioned are probably much better in some ways but for a point and shoot,stick in your pocket and go and traveling lite this is the way I would go.More in line with your Sony Cybershot style.I have a large digital also but don't regularly climb/hike with it.My Casio was ALWAYS with me till someone liked it better than me at a crag.Like just last week.I'll get another Casio this week.
