It helped me increase productivity more than some of the tools we discuss here :-)

I agree, Franz. If you do much writing for a living or for pleasure, it's a very worthwhile investment. (And to any Mac newcomer, confused by the choice of text-replacement apps available, I'd say this: Textexpander is the best, not by a long way, but it's still the best - and I know, because I've bought and used all of them at one time or another.)
