This is regarding formatting the card in the camera vs. erasing images.

A while ago, I've seen recommendations that formatting the card
in the camera every so often helps avoiding problems with
the file system.
I have not seen any arguments about that, and cannot say for sure
if it is true or not with the modern flash cards.

[speculation on]
I do not know the design of the flash memory as intimately as that of
some magnetic memories. So I am not sure (and it may depend on 
the card implementation [?])
- whether there is any type of "toggle-reset" of the cells during 
the format, one that can decrease probability of the charge leakage
from the particular cell, hence improving retaining capabilities.

Also, I am not sure if any check of the cells during format is
implemented; such that would allow marking bad cells (like bad 
sectors in HDDs).  Probably not...
[speculation off]


What I've noticed is that once I start seeing any strange or funky
behavior with the CF card in my P&S digital camera, usually after
deleting of selected images done on many occasions, reformatting takes 
care of it. (This "strange" behavior includes: longer then normal time
to load a picture into the camera while in the review mode; 
any strangeness of the Canon proprietory software communicating with
the camera during the transfer of the pictures from the card
in the camera connected to USB.)

In any case, I do not see any downside for formating the card every
time.

HTH,
