I just got my Eye-fi Geo (2GB) card yesterday and had a little bit of fun with it already, when a thought striked me: the Eye-fi card would be an excellent photographer companion, together with the N900.

Imagine, you are on the field, snapping away your photos happily, but the 2 GB card fills up quickly. If you have your N900 with you, your camera could (even continously) unload the pictures to the 20+ GB storage available on your Maemo machine.

You could review it on the amazing 800x480 screen, you could upload previews to the Net and you would already have a better chance of seeing some blurred/bad photos than on the LCD of the camera.

Currently, this is done on some kind of netbook - but that's not the ideal option.

Question: how can this be working? The Eye-fi card uses wi-fi to upload pictures to a PC/Mac.
