A friend just inherited a Sony Clie SJ130. He's happy as a clam but wants to

So, what's the deal? Will any brand work? Also, what's the difference
between Memory Stick and Memory Stick Pro (and any other incarnations)? And
before you berate me, I searched the web for this information until my
fingers turned blue. It seems to be some closely guarded secret.
