Love the card, the tech is so cool.
I'm mostly using shutter snitch and the X2 PRO. I'm shooting s jpeg to the eye-fi and RAW to a fast Lexar CF. I'm using direct mode, but the error occurs even if the card isn't currently connected to a network and my iPad is off.
I've gotten a couple of error 80s from my 5dmkiii which are entirely new since staring to use the eye-fi card. I've discovered a very reproducible way of getting the error - if I format the eye-fi in camera (not low level). The next shot I take will usually cause an error 80. Then I have to pull the battery to clear the error.
Given the correlation between the format and the error (after that I can shoot mostly reliably again) it seems to be eye-fi related.
I'm tempted to give the beta a try, but I wanted to know if you are aware of the issue or can reproduce it yourselves.
