Much as I like Sony stuff, their habit of going all proprietry has annoyed me enough that my next point-and-shoot camera won't be one of theirs. I got caught out by one of their MicroMV camcorders (I should have done more research on that one) and the ever increasing amount of storage that calls itself Memory Stick is getting a bit confusing; Memory Stick, Memory Stick Pro, Memory Stick Duo, Memory Stick Pro Duo, Memory Stick Micro aka M2. It also doesn't help when most things will fit in an original Memory Stick slot (maybe with adaptor) but wether they work or not is a different matter.

Mind you, much as I'd like to say something about having a bit more of a standard like SD, we have SDHC, mini SD and micro SD, then various bastardisations on a theme like MMC.
