I picked up a 16GB Eye-Fi card and have really been happy with it. Good performance, reasonable capacity and the fact that it automatically transfers pictures to my computer is great. The only problem is that it really drags the battery down when not in connected to my network. That’s probably due to it constantly searching for the network. The simple trick is to turn off the WiFi connection when you’re going to be out and about and want the get the most out of the battery in the camera.
