I have been researching digital cameras for months now and have finally narrowed it down to something in the Powershot SD series. Now I need some advice: Should I go ahead and buy the SD 800 or wait until the 850 comes out?
I know the 850 is actually an upgrade from the SD 700, but I noticed that the 700 got better reviews than the 800. Obviously, I'm not going to invest in the 700 when the release of its newer version is just around the corner, so that's out of the question.
So what do you think, is the 850 going to be that much better than the 800 in terms of improvements over the 700? I just realized how confusing this thread must seem to anyone reading it. Any advice would be great.
