In preparing this year’s 20 Under $20 list, we loved the idea of presenting 20 killer Mac apps you might not know about—20 is such a round, pleasant number, and would hopefully let us find something for everyone. But $20 per app might not seem like the bargain-basement price that it used to, even just back in the summer of 2011, when we did our last 20 Under $20 feature.
But guess what? Most of these polished, stable, user-friendly, and utterly useful applications don’t come anywhere close to a full Andrew Jackson, anyway. Four of them are free, and only two cost over $10. We thought about calling it “18 Mac Apps Under $10 and Also Two That Are More Than $10 But Still Less Than $20, and By the Way, Four Are Free,” but that’s just too long, wouldn’t you agree?
