Fuji loves using the xD system and why not as they are the only ones making memory cards of this type. That's not bad in and of itself, but you can't find them in larger sizes than your regular SD cards or even microSD cards. It fits a Fuji Finepix camera that I bought for use at work and does the job. Using it in the factory allows us to transfer images from the card fairly quickly, so it doesn't fill up quickly. But if I were to use this for a vacation, sporting event, or concert where I wouldn't be in close proximity to a computer to transfer the images from the card, I'd have to buy a few.
