I currently own a Canon A85. It is about 6-7 yrs old. The sensor went bad, but Canon fixed it for free 😀. I have the underwater housing for it and it serves as my underwater camera, although I havent used it since 2007 (last trip where I went snorkeling).
Bought my then fiancee, now wife, a Fuji F31fd for her birthday a couple years ago. This the best P&S camera I've seen. The combination of a larger 1/1.6" sensor and Fuji's SuperCCD does wonders for image quality. Auto focusing isnt upto par with the Canons, but I just love the images I can get out of this little thing. My favorite P&S by far. Newer P&S like the LX3 or G11 might be better, but Ive never used them.
Wife bought me a Canon S3IS a while ago. It's quite a versatile camera, and used to be my main vacation camera. Still alive and kicking, although I dont use it much now.
Finally, I got a Canon XSi a last summer. Love this camera! My main camera now, and my lens collection is slowly growing. Currently own a Tamron 17-50, a Sigma 10-20, and a Canon 85mm f/1.8.
