There is another one: it was made by programmers ;-)
And maybe accountants...

More seriously: Bill Gates (yes, that one) mentioned in his keynote at 
OOPSLA the "universal storage" (I think he called it). I take it as a 
given that MS will screw this up, but as a general idea this is probably 
what you are thinking of relating to MRAM.
There are systems that tried the more query oriented approach (showing 
letters in a calendar so you can access them by date written, Exobox 
IIRC), but I don't know of any that really made it to market.
