OK, here's why it's not stupid to have quotes...
isDefined() replaces ParameterExists(), which required the variable name to
be put in without quotes, in fact, you couldn't (naturally) check for the
existance of a dynamic variable name
isDefined() uses the quotes because it can take dynamic variable names, take
this example;
<cfloop index="i" list="Name,Company,Email,Tel,Fax">
<cfif isDefined(i)>
<cfif Evaluate(i) is "">
<cfoutput>#i# not completed<br></cfoutput>
</cfif>
</cfif>
</cfloop>
Without using an Evaluate() on the first CFIF, you couldn't do this... why
use 2 functions when one will do?
Hope this explains a bit
