TheTechLounge takes a look at the Eye-Fi Wireless SD Card

I'm of two minds on this wireless SD card. It's clever, unique, relatively inexpensive, and essentially universal. It's pretty, in a memory card sort of way. It has a couple of flaws that would be far from deal-breakers if, as a whole (hardware and software) it just did more. Without raw image support, this Eye-Fi creation will never be the memory card for professionals. Without open wireless networking support, it won't help the traveling photographer. The direct-to-online photo service feature is cool, but indiscriminate, posting
every underexposed, blurred up-nostril without remorse.
