I bought the Eye-Fi SD Card from Photojojo (my first purchase from them, actually — a good experience) and it’s spectacular. What a great product! I have some more testing to do, but from what I’ve seen so far, this thing is really cool. Apart from uploading photographs to lots of online services, it’ll also make a copy of your photographs on your computer, basically eliminating the need to sync photos to your hard drive. And the setup was blissfully simple and quick.
