I had 3 AF-P&S, and also used a 4th belonging to a friend.
The Canon Sureshot stooped working at the first roll, during a winter. I’ve put new batteries in it when starting to shot, and also changed the batteries when got back home, but it vain. Still, it came back to life after 2-3 months, but stopped again before finishing the next roll. One year later started working again and continued to work for other 3 rolls, after which I gave it away. I heard it still worked before the person went digital. I do not recommend it.
The Nikon One-Touch is my best P&S. Bought it defective at a church sale, but after opening it and mounting a spring back, I never had a problem with it. It has a low contrast VERY high resolution lens (colors are very natural), and despite the usual behavior of Tessar-type lenses, it works beautiful large open and gets vignetting when aperture closes down. This is why I use it for architecture, street, and indoors where small group portraits are incredibly beautiful. Colors are just like those produced by my YashicaMat. Focus is fantastic, even at f/2.8 and 1m close, on any lighting (even in dark). Two weaknesses: it only gets DX films (no possibility to set the speed manually), and the lens does not accept filters (still, an adapter for filters can be easily found on the bay). I wouldn’t recommend it for winter shots, or any other scenics in plenty of light, because of the vignetting issue. Otherwise, it is the best AF-P&S I’ve ever seen.
A Ricoh 35 AF (or so), with a threaded lens barrel allowing to mount 46mm filters. Beautiful camera, with a high contrast Tessar-tipe lens. It gets vignetting when wide open, although works just fine. I used it especially in landscape for highly saturated colors. Focus only showed errors in total darkness and on dark objects (although it has a red focussing beam). Because it can get filters, I use it in B&W, mostly outdoors. But I also would recommend it for slides, because of its capability to saturate colors. Colors are just like those produced by my Rollei B35.
Yashica T* (4?), also works beautiful. The lens is contrasty and shows a surprisingly high resolution too (maybe the accutance is very well balanced to both saturate the colors and create the feeling of high resolution). Colors are in the Olympus style, if I can say so (I don’t have an Olympus, but I have seen pictures done with a Zuico lens on the same film I was using). The weaknesses of this camera are: the largest aperture being only f/3.5, and the lake of filter thread. But the force, especially during the winter, is that it is powered by large 6V(?) lithium battery (expensive, but long life). I would recommend it especially for slides and/or winter shots.
