Sorry if this has been covered before, but the minimum word length makes searching for xD a pain! 
I've a got a new camera coming for Christmas which takes both CF and xD. I already know that CF is cheaper, while xD is a smaller format.
Aside from those points is there anything else to consider? Which would you guys choose and is it a case of just getting CF because you can get more for you money?
