That all depends on who you're defending against.  Several of the  
methods mentioned won't do any good if the attacker uses force probe  
microscopy to recover your data from tiny bits.  That's TLA govy  
types only so far as I know.

I've heard stories about certain airplanes containing large trunks of  
an acid bath (pH nor type not known to me) into which sensitive  
electronics are dropped when the plane is in danger of falling into  
3rd-party hands.  This method is optimized for speed and  
effectiveness, not cost or safety.
