It seems particularly telling to me that Norvig himself seems to have switched to Python for most work.
Christian Queinnec's _Lisp in Small Pieces_ is another absolutely brilliant book on Lisp, btw. It and PAIP are both about equally expensive, but both are well worth it IMHO. (FWIW, PAIP is probably of more interest to people with no intention of using Lisp.)
(Also: Remapping your keyboard helps, whether you do it in your editor or overall. And, I did not write the above just to say "IMHO FWIW PAIP". Honest. :) )
