NOTE: The CF – SD/SDHC adapter route is not recommended by the vendor… though in some instances it works.
There are mentions that you might want to use the ‘Eye-Fi Pro X2 if you plan use it for a lot of photos because it uses a higher bandwidth (802.11n?). Of course then you’ll need the appropriate ‘basestation’ or ‘WiFi transceiver’ in your computer to be able to use n (both sides have to be ‘n’ compat.. watch out for earlier ‘n’s because they are not necessarily up to standard)
On the other hand, there does seem to be some mention of it pusing things to an outside acct too? See second review down on this link:
It could be that the vendor is trying to do too much with the software.. instead of just simply a wireless image transfer.
