After first writing about it in December of 2007, I finally got a hold of an Eye-Fi card, and now I'm not sure why I hadn't worked harder to get one of these little gems sooner. In my defense they are not readily available in Canada and I really dislike paying the duty that comes with purchasing such things online from outside of the country. I have however very recently obtained an Eye-Fi Connect X2, 4GB+Wi-Fi and there is no turning back... awesome is all I can say. It's very easy to use and the endless memory mode means you never have to worry about running out of memory on your card as it intelligently makes space once your content is safely delivered. The card can be configured to recognize up to 32 Wi-Fi networks and upload content to 25 different photo and video sharing sites.
Not all went smoothly with the installation on my Windows 7 machine, and I understand that my friend and coworker encountered a similar issue on his Mac. The documentation that comes in the package is sparse, to say the least, but luckily the support forum was easy to navigate and assisted in getting me over the hurdles. It seems as though we both had issues with the "helper" application that analyzes your network and firewall settings. Once resolved the Eye-Fi has performed flawlessly and is my new favorite gadget.
