SD already is a sort of de facto standard for storing material on all sorts of
gadgets, mostly pocket ones, though I suspect it is used a lot less frequently
for exchange of data between gadgets, because mostly people just want to swap
the occasional snapshot, and they can use bluetooth or MMS for that. For
swapping stuff between computers, the USB dongle drive seems pretty popular.
Whatever is cheapest and easiest to use will always be the one most people
use, and in five years time there will be something completely different, and
Sony will invent their own incompatible version of the same thing, then a
smaller one that needs an adaptor, and so on.
