TextExpander has been around for a long time. I'm using version 5, i.e., the fourth major version upgrade. There's little or nothing else that needs to be added to the product at this point. They charged an upgrade fee for new major versions. IIRC, it was $19.95 to upgrade from v4 to v5. I didn't mind paying that, even if the new features were minor (I can't even remember what they were -- and I think I actually upgraded only because v4 wouldn't work anymore on a newer version of OS X, though my recollection could be wrong). That's the life-cycle of software products sold on the traditional model. At some point you need to realize you've wrung all the money you can out of upgrades, and if the revenue from new sales and (increasingly rare) major upgrades isn't enough to live on, well, you better develop some new and different products. Of course it's better for you as a developer if you can convince people to pay you $60 per year in perpetuity for your small utility app, rather than just collecting a one-time $30 sale and occasional upgrade fees, but just because that's your super-dream-fantasy business model doesn't mean it makes any sense for customers.
