My opinion.
I just got back from Africa, I took with me a Canon s5 IS that I got for christmas. This camera ROCKS. I was asked which camera I would pick and why before the gift was purchased, I picked the s5 for the following reasons
12x zoom. This kicks the crap out of a 4x or even a 10x, it is equiv to 36-432mm 35mm standard.. this is bloody amazing, you would need at least two lenses to get this kind of zoom out of a digital slr with any decent apeture.
previous experience. I was in central america last year and a guy I met had an s3. It had been dropped, beaten and it was durable. This made a major impression on me. So in short, its durability impressed me. This was reinforced when I took my new s5 to africa and beat the shit out of it, I got some GREAT photos (better than the lady with the nikon slr) and was super impressed by its movements, even when filled with dust.
SD memory... some of the others use weird standards, sd is pretty much the universal
Battery power - 4xaa and they last for a LONG time. Note though, I did use the viewfinder most of the time which cuts down on battery drain.. not using the LCD. I like this because pretty much no matter where you go you can find aa's and you don't need to rely on some stupid travel adaptor to charge a proprietary lithium ion battery. I was using duracell ultras and pulling over 600 pictures per set, and some videos too
Videos - The videos come out awesome, and the sound is equal to the video quality
Accessories - You can get an adaptor ring and set this sucker up with telephoto and wide angle lenses. I haven't got any yet but I will be next payday. This makes it equally (imo) versatile as digital SLR's.
The only cons - size. It doesn't fit nicely in the pocket
and the batteries - consumable so you're throwing things away.. but this is eclipsed (got some good photos of that) by the fact that you can get the suckers everywhere and are rarely stuck without battery power and missing photo ops.
The cons are way outweighed by the pros which make it an awesome awesome piece, and the reviews out there on the web back up what Im telling you
I also should add, that the people on my safari were so impressed with it, that a few of them bought them while on vacation, just so they could get that unforgetable shot of the lion, or the hippo.
Anyways, good luck, picking toys is the best way to waste time
