Is WiFi on the F800EXR of any use?

I was thinking less of a camera which has built-in wifi (as with gps, that strikes me as a bit of an abomination) as an SD card that has one. Looking at the descriptions of the wifi SD cards out there, it seems to be kind of as I described, but if that were so, why would there be need for dedicated software applications for them? (Also, customer reviews seem at best mixed, which is why I asked if anyone had one that was reliable.)
