Question

I have Windows XP - does Canon SD850IS 8 MP w/4X Optical work on my computer - I read in some of the specs that it only worked on Windows VISTA. If that is correct, which ELPH do you suggest I get for XP?I have a NIKON D50 SLR now but looking for one to carry in my purse every day - I'm always finding photo opportunities. Thanks - Nell
