Eyefi is a really cool idea, add a wifi chip into a standard SD card, so that when you walk into your house, turn on your camera, all your photos are synced to the cloud. During this trip I finally also got the mobile link mode working, where your phone acts as a relay, which meant from Halifax on I was posting pictures up to friends on facebook during the trip.

It does this by starting up a wifi hotspot after the camera has been on for 30 seconds (and hasn’t found a wifi network it knows). You set up that hotspot on your phone, and because the devices are so close, it’s the dominant signal, and your phone auto jumps to it. It pulls down all the photos yet synced, then the AP goes silent, and your phone goes back to normal. Next time you wander onto a wifi network, your phone then relays those up to your chosen cloud sync point (many are supported, including google, facebook, smugmug, flickr, or your own gallery 3 installation).

If you have a camera, you should get an eyefi card. I really can’t imagine going back to having to sync photos through a PC any more.
