Not everyone.  While you could do overlays on the 1108 and successors, 
it was infrequent.  But using multiple banks was easy and convenient. 
An nice advantage of banking is that you could put shared libraries in 
their own banks, so you didn't have to worry about figuring out how to 
address them from the main program (as well as reducing the size of the 
main program banks).  But I agree that nothing beats the simplicity of 
large linear address spaces.
