Aah, that's a bit pessimistic. Even for a regular flash.
It is true that the number of write cycles varies between cards. Some vendors have both consumer and industrial grade cards, and the industrial grade ones use better parts inside.
However, I have yet to see a CF card which didn't survive beyond a million writes.
Note that CF cards do transparent wear averaging inside. So it's obviously not a million writes to the same physical spot. Also, most vendors claim they have spare blocks for relocating areas that are completely worn out.
So while a Compact Flash isn't a hard disk, it is at least a couple of orders of magnitude better than "hundreds of writes".
