Well, not really for backup but for those times when you don't really feel like carrying your SLR/DSLR. I've been kicking around the idea and read up on the following so far: Nikon P6000 I like that this one could use my existing flash units that I use on my D90 (SB400 and SB600) and the fact that it has a built in GPS (something I enjoy on my D90 as well). Canon G10 Seems to be the winner in most all reviews, I personally don't care for the controls but haven't played with it very long. Panasonic LX3 Haven't seen one in person but seems to be missing some features I'd like, such as aperture priority. Canon SX110 This one is my favorite so far for price/feature ratio plus it seems like fast glass for a P&S and the zoom is impressive (36mm-360mm optical).
