Sony. You use PS3 or PC as a gateway to media, download to MemStick, play on PSP, put MemStick in Sony camera, take photos, put MemStick in Sony TV, view photos, put MemStick in PS3, save games.
A CF or SD solution that does the same would be cheaper, so MS and Ninty could compete in that area (assuming some sort of Media player, which Nintendo might introduce with GBA2?) with price along with functionality, and support other devices, not just their own brand (unlike Sony, where you need a Sony house to fully live the Sony way).
It's be an excellent idea to support all those old camera memories that people have outgrown with newer larger sizes, giving access to lots of free storage for the console.
