Back when we reviewed Eye-Fi, the SD card that allows any digital camera with that slot to wirelessly upload pictures using a home router, we were impressed by its speed and ingenuity, but wished we could use it while on the go. Looks like the folks over at Eye-Fi heard our complaints (and others’). Today, Eye-Fi announced that it will sell its popular card in three forms, starting June 6th (sorry, no upgrades for early adopters). Eye-Fi Home ($79) costs less than the current version, but offers less features; it syncs with your PC, but not the usual host of Web services. I’m not sure this is different enough from a regular SD card to warrant the $79 price. Eye-Fi Share ($99) is essentially the current model with a new name; it syncs with both your PC and photo sharing sites, such as Facebook and Flickr. Eye-Fi Explore ($129) is the real news. Thanks to a partnership with Wayport, users can upload photos at more than 10,000 hotspots nationwide. The Explore also has geotagging capabilities, using Skyhook’s Wi-Fi triangulation. Up next on our Eye-Fi wish list: More hotspot partnerships, and the ability to upload video clips.
