Solid state memory is totally obviously the way to go. No moving parts, low power consumption, the option of ROM, RAM or Flash types, and it's compact & portable. Mass marketing will drop the price until it out-competes everything else. It's inevitable.

I can't imagine cell phone makers will keep MP3 and Camera phones separate for long. Expect a phone that does it all in the near future.

Maybe two, for stereoscopic 3D graphics. It's coming... if I can think of it, so can somebody else. It's a totally gonzo cybergoth futurefantasy concept.
