Eye-Fi Pro X2 Wireless SD Card, $87
Eye-Fi Pro X2 SD Cards let you use Wi-Fi to transfer images straight from your camera to your computer, or post them to a website. The cards hold 8GB of data and can handle JPEG, RAW, and video uploads. (Read "Eye-Fi Pro X2 Increases Capacity and Speed" for more info.) When the Eye-Fi Pro X2 card launched a couple years back it cost $150. Prices have fallen since then, of course. For a limited time, Amazon.com has the best deal I could find: $87 for the Eye-Fi Pro X2, with free shipping.
