Just waiting on dleivery of my girlfriends Xmas pressie (Sony W12) and wan to buy some extra memory to go with it. I understand the camera will work with both Memory Stick and Memory Stick Pro. I know Pro is faster, but will this only affect things if I am using video on the camera? We are not going to use the camera for video much, if at all, and I dont want to buy the Pro if I dont really need it. Also, where is the best place to buy from? I see there are some good deals on them on ebay, but mostly shipped from Hong Kong. I was looking at 128mb or maybe 256mb. Also, whats the Duo all about and can it be used with the W12?!? Cheers for any advice.
