@PubuduR – The camera I use has a setting for Eye FI card; this has an option that could turn off wifi on your eye fi card. I am sure this is for safety and battery savings, but I'm not sure if there are other ways to turn it off.
@Richard – I think not most of us make the best out of this gadget. I think its meant for professionals and photo maniacs (I am one of them). Most of us don't carry our camera everywhere we go, the easiest is the smartphones with camera.
@NadineJ - look at the pixel rate, exposure settings, shutter speed etc before you make the decision on buying an SLR or DSLR. Once you get a good machine (DSLR) it's about choosing a good lens to make the best out of your camera. Personally I prefer Cannon DSLRs for most of the above reasons.
@Shadetree – good suggestion on keeping the card away from the authorities. I am sure the distance should be less comparative to other wifi devices as this transmission need power from camera battery, if the transmission is powerful it will drain the battery soon.
