Eye-Fi also markets the Mobile X2 ($79.99, 4 stars) and Pro X2 ($149.99, 4 stars) memory cards, both of which hold up to 8GB of photos. Using the card eliminates the hassle of connecting your camera to your computer via an often-proprietary cable, or removing the SD card for use in your PC's card reader. Most current cameras are compatible with Eye-Fi cards, but if you have an older model you'll want to check on its compatibility. You can also configure the Eye-Fi card to upload photos to photo sharing sites, including Flickr, Picasa, and Facebook. It features a Wi-Fi modem, compatible with 802.11n networks, that makes it possible to wirelessly offload photos from your camera to your computer, Android, or iOS device. The Eye-Fi Connect X2 ($49.99 direct) is a 4GB memory card for digital cameras.
