I am a digital photgraphy newbie and I quite fancy the Sony Cybershot DSC P200 but not too sure about the Sony proprietary Memory Stick. They seem a lot dearer than e.g. SD memory but I may put up with that if there are no other downsides. I am wondering are outfits like Boots likely to have Memory Stick compatible readers, if I don't want to use my own photo printer? Any other Memory Stick downsides? (Availability of replacements in Tibet? ;-) TIA
