The is actually a performance gain on text fields in regards to inserts,
so even in cases where you *think* that something wont go over n
characters if your application doesn't require it, you might want to
stick with text.

the main downside most people would mention is that "text" data types or
not sql standard so you might have a problem porting to other DBMS (not
that you'll want to d:] )
