He's one of very few guys to whom I'd say "This area around Q17 and Q18 
is critical, it's RF stuff" and he'd respond "Yeah, I already saw that 
in the schematic and took care of things". The board before this one had 
even more parts, >600 or so IIRC. Had ten boards stuffed, plugged the 
first one into the system -> Worked!

Professional layouters do care about their work because the results 
reflect back on them.
