Incompatibility Issues (Score 1)

Is no one else thinking that this is something else that can be incompatible with everything else on the market. I can just see myself walking into a store and asking for RAM. "Would you like EDO RAM, SDRAM, MRAM? Do you need PC100, PC133, PC200?" I know PC200 isn't out yet, but it's coming soon. I just see all this new technology, and none of it is compatible with the current technology.
