hey guys i'm heading off to college and would like to bring a digicam with me...this will be my grad gift
i was concerned about the picture quality and the built quality between these two models... i know the 870 has only 8mp and 3.8x optical while the 790 has 10 mp and 3x optical...i'm pretty sure all the technology is the same the only differences are those two specs i listed above...
which one would you guys recomend? which is more sturdy? which one takes nicer functions? do each of them have different functions?
also although the 870 is an older model vs the 790 is there really any major differences between them?
thanks!
