Simon_84 said:S2 has the metallic body thats why you would have firmer grip on this heavier and bigger body but the sales package doesn't come with carrying case which is a big turn off when you are unable to store the camera properly in some place.
and it doesn't come in black colour as well only sliver.
S2 IS body is also plastic. THe weight comes from the 4 x AA NiMH batteries that you need to use it with.
