It's not the cost of replacement that's the issue for me - it's the sudden inability of the card to retain information, the time (without a working card) that it would take to replace the card. On the bright side though, such an event can be just the thing you need to "justify" the upgrade you've been wanting but couldn't otherwise justify.
The problem is similar to that of nonvolatile ram used in modems to retain a "user" configuration - a limited number of writes. I know someone who accidentally added the "write" command to his modem initialization string. After about 1000 initializations, the modem would no longer retain the configuration.
