You are right, but it's also important to lookup the specs of the CompactFlash card before buying it. How they actually do wear-levelling differs, and I've heard of brands which perform wear-levelling only within regions of the disk - not over the entire disk.

In such cases, you can still wear out the flash in "reasonable" times. There are also some brands (I know of SiliconSystems) which allow reading CF-internal wear-levelling data (spare blocks, number of erases etc), although I'm not sure if there is any non-proprietary software to actually use this.
