To be able to tether wirelessly into iphone/ipad if very helpful to me. This
is something I regretted for not having it sooner. Agree to what have been
said above, it is slow to copy from the card to computer. I accidentally
shot an video onto it and it takes so long to download. The wifi need some
setup to go through. I scratched my head quite a bit at initial set up. my
camera has two slots, so i am shooting jpeg 1920x whatever on eye-fi, and
raw on compact flash. I am not even shooting full size jpeg, just to make
the transmission faster.
