Eye-Fi today added both a new card and a major expansion of its support for hotspot cards. The 4GB Geo X2 combines the geolocation support of the original Geo with the Class 6 (6MBps) transfer speeds, 802.11n Wi-Fi and "endless" memory of other X2 cards. It's targeted primarily at Mac users using Aperture 3 or iPhoto '09 and will be available only through Apple stores in May for $70.
