Over the years, manufacturers have come out with more and more flash memory formats, and none of them are any better than the others. SmartMedia, CompactFlash, Secure Digital (SD), MiniSD, xD, and all the different flavors of Sony's Memory Stick (Pro, Duo, etc...). The worst are xD, and Memory Stick, because they cost so much more per megabyte and offer no advantage. It's just a way for them to make more money. Sony leverages it's market share in a wide variety of electronic devices to promote its own memory format and charges a premium for its memory. If you have a PSP, Sony Digital Camera, or Sony laptop, you'll probably be buying a Sony Memory Stick at some point. Their memory of course doesn't work in any other brand's devices so you'd have to buy more flash memory for your other devices to accommodate the different formats.
