"First SD flash memory card with integrated Wi-Fi coming" Could this work with eCS? I have a sd adapter that I use with sd cards and the eCS Thinkpad T23. One reply to the article indicates 'this card does not require a specific OS, like the Sandisk or others for palm. It is a file server in your camera that does not need software or driver in the camera.".
I haven't tested that item and so far only read about them; but DpReview (http://www.dpreview.com/reviews/eye-fi/) has a review of mentioned item. DpReview is also among the best site when it comes to camera reviews, etc.
