I simply cannot recommend any Eye-Fi card, even the fancy new X2 line, to average camera users. Even enthusiasts like me would be wise to curb their enthusiasm. Most features barely work in practice, and the device frequently failed to perform.
Eye-Fi (the company) would rather that we focus on the capabilities of their card rather than its technical components. But any self-respecting geek is going to want to know what makes it tick! I’d rather not cut open my card to get a peek at the chips inside, but Eye-Fi released some official details about the components used in the X2 series of cards, and a quick Google search revealed all that I needed to know.
Buyers of 802.11n wireless network equipment should not assume they will see a great benefit right out of the box. Most will have to enable by hand a high-performance configuration including wide channels and 5 GHz operation.

One reason the smartphones like the iPhone are gaining ground on purpose-built cameras is their instant connectivity: Take a photo and you can immediately share it on Twitter, Flickr, Facebook, or other popular sites.
