Title: A GREAT card, but might be overkill.
Review: I gave this card five stars because it deserves it. It is fast, able to take extreme conditions, and probably less susceptible to corruption than cheap cards. However, a fast card may be of little to no benefit in the real world. After all, your camera can only write to the card so fast. This is why the Extreme III is of little to no benefit compared to the Ultra II in a Rebel XT/XTi. And if you use a card that is faster than the camera, you are likely spending more money than you have to. Unless you need the ability to withstand extreme conditions, the Extreme III is just overkill.On the other hand, you can read data from the Extreme III faster than the Ultra II. So you will be able to download your images more quickly with the Extreme III. But you have to ask yourself whether the time savings justify the higher price.
