as i have said before, ive researched cameras for a while, and i thought this one was the best. True, there are some other cameras that are also small and good quality, but i thought this had the best image quality/size combination. canon does have the slightly bigger s300, s30, and s40. the s300 adds 3x zoom(which i dont think is too big of a deal.....), and also the s30/s40 are 3/4 mp respectively...however, my eye is not keen enough to see the difference in MP..as i am just an ameteur. i used to own an olympus c-3040, but i sold it because i wanted something i could carry with me at all times that is rugges as well. for some reviews of cameras, these are some good sites.
