Last year I got an Eye-Fi card (a wi-fi enabled sd card if you're out of the know), and while it certainly had a wow factor, wasn't particularly useful when transmitting larger images to my, and was pretty much useless when shooting in raw unless I bucked up for the pro version. Well, it's been redeemed in my eyes now that I have it in my p&s, and finally figured out how to use the apps that allow me (or you) to shoot from whatever camera the card is in, and transfer it to your android (or probably iphone/ipad), where you can then edit and upload w/o your computer. This certainly makes for a nice ability to bypass the "wait till I get home" phase of sharing photos.
Just thought I'd share.
