I put together a WAP using CF as the harddrive last year - since all the logging is mounted externally and I netboot I can just open up the case and pop another CF in if one goes bad. I can't actually say that I've had any real performance issues or that I've had a card die - the WAP only has to manage about 15 mbps and the only writes occur when the device reboots.
For a few years prior I used 2.5 inch notebook drives which, despite operating at idle just about all the time, had a very high attrition rate.
I think the capacity limitations of CF(I/II) make them appear less attractive to me than SSD drives, but I haven't seen any solid evidence that CF, which requires very little by way of power (3.3 or 5 volts), has a defined lifespan limitation.
