I agree about the potential for oddities creeping in ... and the only 
way to work with them is to re-initialise the kernel and clear down 
state fairly frequently. The integration of so many packages for 
displaying data etc makes them (fairly) straightforward to work with if 
you want to (e.g) get a quick look at that spectrum you just removed 
background from or whatever.

To those of us who tried to run research programs using punched-cards.. :-)
