I've been meaning to pick up a new SD card for the camera for ages but haven't got round to it. I've been using a 1 gig card ever since I bought the camera and as I shoot in highest-resolution jpg* that gives me just 250-odd photographs per shoot. This is great discipline because I focus on getting the right shots instead of 100s of mistakes. However, with lots of shoots getting booked it's good to know that I can do two shoots back to back without having to download the files.
*I would love to shoot in RAW but my poor little iBook would struggle to open the files :(
