Is the Memory Stick Duo the only storage card I can use with a Sony Cyber-Shot?

I was thinking about the Sony Cyber-shot W170, but it only says you can store pics on a memory stick duo card. Are they not at all compatible with SD cards? And how do you get pics to a computer with one of these "sticks"? The label on the slot I use for my SD cards says "SD, MS/Pro, MMC, XD. Would I have to buy more equipment just to be able to transfer pics to my computer?
