Casio Exilim S500 and Z500

[Paul_T]

Been thinking about getting either of the above. Does anyone actually own one? If so what are they like? I haven't really found any good reciews on the Z500 but I've read a few on the S500 (which I like more for it's card like size) and most of them say the image quality isn't too good and there can be image noise. I only really want it for simple, fun pictures. Is the noise really that bad?

Would I be better to go for something like the Samsung i5 which I've also had my eye on?
