I've heard about the Eye-Fi SD cards for some time now, and they seem like a really nifty solution for wireless data transfer, geotagging, etc. What I haven't been able to figure out, though, is why this card is only available in the SD form factor. You would think that if they made a CF version, DSLR owners would be all over it. I know I would! I would gladly trade some capacity for the ability to seamlessly transfer photos over a wireless network, and/or have integrated GPS tagging.


So what gives? Anybody have an idea why such a thing does not yet exist? You would think it would actually be easier to do, given that SD is much, much smaller than CF.
