None whatsoever.... ;-)

But not a good idea to keep CFs and heavy batteries loose in a solid case
and shake them all around....
It is a must to keep CF cards in their cases though - they don't like dust +
fluff etc. in their connectors.

I have one compartment in my briefcase to store these things. Is there any
reason why not to put spare CF card/s next to my spare battery/s?
