Raid, one consideration may be an optical VF if your travels will take you so places where the sun shines.
I always have my Fuji F30 with me but if it's sunny the LCD is difficult to use. If I know I'll be shooting outdoors, I take my Fuji E900 or S6000fd instead. The E900 is bar soap sized and has a VF. The S6000fd is not pocketable, but has a very useful EVF.
All these cams use essentially the same relatively large sensor which provides remarkable perfomance at higher ISO and thus gives you more flexibility than other P&S cams. You could walk into a museum and make good pix with available light, then walk outside and do the same in the blazing sun with one small camera. One negative; none of them have any form of image stabilization.
I've yet to find current models that can equal their performance at higher ISO -- including the vaunted LX3 and S90.
