You need to buy a card and a much bigger one if you don't want to be constantly deleting stuff. I would consider 16gb the minimum. I have a 32gb class 10 GSkill that seems really fast for video and burst modes, but the same size Patriot and Mushkin class 10 cards are much slower and make the camera seem unresponsive. I even had to RMA the PAtriot one it was so slow, but the new one is acceptable. I got the GSkill on sale for $9.99, just watch New egg, they go on sale all the time. The faster the card the better. I will try a SanDisk Extreme when the price comes down.
