High end compact camera

My canon IXY Digital 900IS compact camera that I got 2 years ago has served me well but the picture quality seems to be deteriorating over time. I think there is extra light seeping through the gap that appeared when I dropped it ^^;

Cant carry the Kiss 2 around with me everywhere due to the size so think I want to go for what they call a "High end compact camera."

Here are some that I'm looking at. Most of these come with the ability to attach wide lenses which is a must. Anybody have any advice as to what I should go for?
